  • Radiative energy transfer via surface plasmon polaritons around metal–insulator grating: For better understanding of magnetic polariton

    Kazuma Isobe, Yutaka Yamada, Akihiko Horibe, Katsunori Hanamura

    Journal of Thermal Science and Technology   19 ( 1 )   2024

     More details

    Publishing type:Research paper (scientific journal)  

    A conventional metal–insulator nanograting has the potential to transmit near-infrared thermal radiation because an electromagnetic wave is resonated in the grating structure. Surface plasmon polaritons (SPPs) take place at the interface between the metal and the insulator with boundaries at both ends. Physicists formulated the resonance frequency of the grating from the Fabry–Pérot interference between the grating thickness and the wavelength of SPPs in a short-range coupled mode. On the other hand, engineering researchers often use a lumped-element model assuming a resonant circuit consisting of an inductance of metal and a capacitance of metal-insulator-metal grating structure. Furthermore, they have considered that the resonant circuit excites a strong magnetic field independent of SPPs. This study compares each physical model and numerical simulation results, then clearly shows that all resonance frequencies and features of the circuit resonance can be described by the Fabry–Pérot interference of the SPPs in short-range coupled mode. Moreover, the estimated resonance frequencies obviously correspond to the local maxima of the transmittance of the nanograting with the various thicknesses and pitches. In this case, a strong magnetic field can be observed in the insulator layer as if it might be an isolated magnetic quantum. However, since materials show no magnetism at near-infrared frequencies, the magnetic response appears due to the contribution of SPPs.

  • Production and Characteristic Measurement of Latent Heat Emulsion as a Phase Change Cold Storage Material

    MATSUZAKI Shun, HORIBE Akihiko, YAMADA Yutaka, ISOBE Kazuma

    Transactions of the Japan Society of Refrigerating and Air Conditioning Engineers   advpub   2024

     More details

    Language:Japanese   Publisher:Japan Society of Refrigerating and Air Conditioning Engineers  

    In this research, we focused on the latent heat emulsion to investigate the creation of phase-change cold storage material that maintains fluidity below 0 ℃. The D-phase emulsification method was used to generate the emulsion. And it was generated by using an aqueous solution of ethylene glycol as a dispersion medium and dodecane as a phase change material. The experimental results showed that a fine emulsion was generated by using polyoxyethylene (20) sorbitan monooleate and sorbitan monooleate as surfactants. The average particle diameter of the sample was approximately 0.24 μm. Additionally, from an evaluation experiment using the sample, it was ascertained that the sample could maintain emulsified state for 90 days and it could remain fluid even when the phase change material in the sample was solidified. Moreover, it was revealed that the sample had approximately 60 mJ/mg enthalpy of fusion from the measurement result of a differential scanning calorimeter.

  • Water/ice mixture- and freezing-front motion in a non-isothermal liquid bridge

    We experimentally investigate the water/ice mixture- and freezing-front behavior in a water liquid bridge under isothermal and non-isothermal conditions. We find rapid propagation, temporary suspension, and regression of the water/ice mixture front, and finally, it merges with the freezing front when part of the liquid bridge is higher than the freezing temperature. However, freezing-front propagation follows dendritic ice formation, and a protrusion forms at the middle of the liquid bridge as long as the whole liquid bridge is lower than the freezing temperature. We explain those phenomena by quasi-stationary heat-transfer considerations.

  • Analysis of Evaporation of Droplet Pairs by a Quasi-Steady-State Diffusion Model Coupled with the Evaporative Cooling Effect

    Publishing type:Research paper (scientific journal)  

    Multidroplet evaporation is a common phase-change phenomenon not only in nature but also in many industrial applications, including inkjet printing and spray cooling. The evaporation behavior of these droplets is strongly affected by the distance between neighboring droplets, and in particular, evaporation suppression occurs as the distance decreases. However, further quantitative information, such as the temperature and local evaporation flux, is limited because the analytical models of multidroplet evaporation only treat vapor diffusion, and the effect of the latent heat transfer through the liquid-vapor phase change is ignored. Here, we perform a numerical analysis of evaporating droplet pairs that linked vapor diffusion from the droplet surface and evaporative cooling. Heat transfer through the liquid and gas phases is also considered because the saturation pressure depends on the temperature. The results show an increase in the vapor concentration in the region between the two droplets. Consequently, the local evaporation flux in the proximate region significantly decreases with decreasing separation distance. This means that the latent heat transfer through the phase change is diminished, and an asymmetrical temperature distribution occurs in the liquid and gas phases. These numerical results provide quantitative information about the temperature and local evaporation flux of evaporating droplet pairs, and they will guide further investigation of multiple droplet evaporation.

  • Natural convective heat transfer from a heated horizontal disc with heated hollow cylinders: Effect of flow characteristics around heated cylinders with a gap

    Rikio Shimoyama, Yutaka Yamada, Kazuma Isobe, Akihiko Horibe

    International Communications in Heat and Mass Transfer   146   2023.7

     More details

    Publishing type:Research paper (scientific journal)  

    The natural convective heat transfer from a heated horizontal disc with gapped heated hollow cylinders was investigated experimentally, forming the foundation for improving the cooling performance of the heat sinks. The cooling target for this study was the central area of the heated horizontal disc where the heat dissipation was low. The heat transfer was greatly enhanced by the reversal of the flow from the gap between the heated hollow cylinders towards the heated horizontal disc. The reverse flow was promoted by the conditions of a narrow clearance between the heated horizontal disc and the heated hollow cylinder and a wide gap between the heated hollow cylinders. Conversely, for the flow along the heated horizontal disc, the heat transfer showed improvement by increasing the clearance between the heated horizontal disc and the heated hollow cylinder. The relationship between the heat transfer and flow properties was demonstrated using the Nusselt number of the heated horizontal disc and the Rayleigh number corrected for the ratio of the heated hollow cylinder height to the clearance between the heated horizontal disc and the heated hollow cylinder.

  • Synthesis and Characterization of Silica-Encapsulated n-Tetracosane and the Effect of Surface Modification by Silane Coupling Agents

    Publishing type:Research paper (scientific journal)  

    Microencapsulation of n-tetracosane, whose melting point is approximately 50 °C, in a silica shell has been performed through the sol–gel method using tetraethyl orthosilicate (TEOS) as the precursor for silica-shell formation. Additionally, two types of silane coupling agents were used to modify the surface of the microcapsules to change the wettability. The morphology of the microcapsules was observed by scanning electron microscopy. The chemical composition was characterized by Fourier transform infrared spectroscopy. The results confirmed the presence of n-tetracosane and silica in the synthesized microcapsules. Wettability analysis showed hydrophobic and hydrophilic features because of the added silane coupling agents. From the results of differential scanning calorimetry measurements, the encapsulation ratio of the microcapsules increased with decreasing TEOS/n-tetracosane ratio, and the highest encapsulation ratio was 87.1 % at a TEOS/n-tetracosane ratio of 0.25. The pH in the microcapsule solution was affected by addition of a silane coupling agent, and shifting the pH to the basic side lowered the encapsulation ratio owing to enhancement of silica condensation. After 100 differential scanning calorimetry cycles, there was no significant degradation in the phase-change temperatures and enthalpies, which confirmed the good phase-change stability and repeatability. Therefore, the microcapsules are a potential material for thermal-energy-storage systems to effectively utilize energy.

    Microencapsulated n-tetracosane as a phase change material with an inorganic calcium carbonate (CaCO3) shell has been synthesized through a self-assembly process with varying pH value of a precursor solution, and the resultant materials were systematically investigated. Spherical microcapsules with a mean diameter of less than 3 μm were seen by microscopic observation. X-ray diffraction analysis revealed the presence of three CaCO3 polymorphs such as calcite, aragonite, and vaterite in the shell, and these compositions depended on the solution pH. This fact was also confirmed by Fourier transform infrared spectra and reflected in the surface morphology of microcapsules. The characterization of the phase change behavior has shown no significant change in the phase change temperatures and more than 170 mJ/mg of phase change enthalpies with the microcapsules synthesized at pH = 1. This enthalpy corresponds to 69.2% of encapsulation efficiency which is improved from the value reported by other microcapsules with CaCO3 shells. Thermal cycling analysis exhibited good reliability and durability of phase change phenomena in the long term. These results demonstrate a promising potential of microcapsules for developing thermal energy storage materials at a mild temperature range, which can be applied for waste heat recovery applications.

    A spraying system was constructed with a microencapsulated phase change material (MPCM) slurry as the working medium to weaken the adverse effects of the slurry's high viscosity and low thermal conductivity on heat transfer in a wall tube heat exchanger. The temperature distributions of pure water and MPCM slurry were first obtained through infrared thermal imaging in spraying. Furthermore, the latent heat use of MPCM slurry was investigated through a new method based on the temperature properties of the phase change fluid, in which the working and phase change temperature ranges are matched. The heat-mass transfer characteristics are compared and discussed with those of the base fluid, and the latent heat use of 10wt% MPCM slurry containing the core material n-docosane (C22H46). The experimental results indicate that the phase change enables the MPCM slurry droplets to maintain a higher temperature than a fluid with no phase change or base fluid. Different application modes (static and spraying) have correspondingly different phase change temperature ranges owing to supercooling, and the degree of matching between the working and phase change temperature ranges has a critical impact on the latent heat use of the MPCM slurry. Finally, comparing the heat transfer coefficients and Lewis numbers between the base liquid and MPCM slurry reveals that the phase change not only enhances the heat transfer but also slightly reduces water evaporation compared with pure water spraying.

    Droplet transportation using a wettability gradient surface has attracted much attention owing to applications such as in microfluidic devices. A surface with a spatial structural gradient was prepared through a simple and cost-effective process even though understanding of droplet behavior on the structure was still limited. Here, we report impinging droplet motion on a gradient wrinkled surface. Surfaces were prepared through hard film deposition on soft pre-strained polydimethylsiloxane (PDMS) with a mask installed with a slit to control the amount of deposition, which is related to the wavelength of the wrinkles. Droplets were impinged with varying position with respect to the structure, and the droplet motion was observed in the direction away from the region under the slit. We found an asymmetric contact angle and alternate motion on both sides of the three-phase contact line during the motion according to the gradient of the wrinkle wavelength. These results may help not only to understand the behavior of droplet impingement on a gradient structural surface but also to further develop applications using directional droplet transfer.

    Microencapsulated phase change material (MPCM) slurries are energy-carrier fluids. Their latent heat utilization has been investigated by a new method based on the temperature properties of the phase-change fluid, in which match of the working and phase-change temperature ranges is considered. Based on the working-temperature range (3–15 °C) in heat-exchange circulation, the dynamic heat-transfer characteristics and utilization of the MPCM slurry with the core material n-docosane (C22H46) are discussed. The experimental results indicate that the effects of the stirring rate and flow rate on the dynamic heat-transfer characteristics are similar to those of water, and they have little influence on utilization of the 10% MPCM slurry, whereas the corresponding effect of the concentration is relatively large. When investigating the effect of the concentration, it was found that a low phase-change ratio suppressed movement of the phase-change-temperature range owing to the residual solid core material acting as a crystal nucleus, while the heat-transfer performance and latent heat utilization of the MPCM slurry suppressed each other. The 10% MPCM slurry is the most suitable energy carrier fluid, but supercooling still needs to be resolved. The experimental results provide a reference for practical efficient application of MPCM slurries as energy carrier fluids.

    Phase change materials show great promise as a way of thermal energy storage. A number of alkanes and these mixtures with melting point below 50 °C have been investigated to develop the microcapsules. However, there have been few investigations aimed at harnessing heat from environmental temperatures around 50 °C. Here, n-tetracosane, which has a melting point of 51 °C, was successfully microencapsulated in a calcium carbonate shell through a self-assembly technique. The structural characterization was conducted by the method of Fourier transform infrared spectroscopy and energy-dispersive X-ray spectroscopy. The encapsulation ratio of the phase change material into the shell was estimated based on the mass loss of the microcapsules due to heating and the differential scanning calorimetry analysis. A maximum encapsulation ratio of 53% was achieved, and the effects of the encapsulation ratio on the effective thermal conductivity of the microcapsules were evaluated by a steady-state method. In addition, heating–cooling cycles were demonstrated in composites of the microcapsules and building plaster. Repeatable thermal energy storage and release characteristics were achieved suggesting that this material is a potential candidate material for management of high temperatures.

    This paper deals with the characteristics of a straight pipe inner flow of the nanosuspension that has non-Newtonian viscosity. The parameters are set in the mass composition of 10–20 mass% of dispersoid and in the temperature range of 20–70 ℃ that includes the melting point of tetracosane. The experimental study is carried out by using the flow pressure loss measurement apparatus. The test section that made of a stainless straight pipe has an inner diameter 8 mm, and it has the length 1000 mm. The inner flow of a straight pipe is occurred by using a pump that is controlled by an inverter. The pressure drop is measured by a differential pressure gauge. The measured pressure loss is used for the calculation of the flow friction loss coefficient and the pump power. The experimental data are evaluated by the variation of the pressure loss coefficient with Reynolds number that defined by the non-Newtonian behavior. Viscosity data by previous study data that correlated by the power law method are used for Reynolds number calculation. The viscosity including non-Newtonian characteristics had been estimated by using a rotary viscosity meter. The measuring ranges are shear rate <500 1/s and temperature 10–84 ℃. The calculation data from experimental correlation equation, which was adjusted by an exponential law, are used for Reynold’s number. The flow friction loss coefficient and the pump power are estimated by measured flow pressure loss. The heat transport amount is calculated by the sensible heat and the latent heat of nanosuspension. The thermal property data (specific heat and latent heat) are the obtained data by previous study that measured by using differential scanning calorimeter. The relationship between the heat transport amount and pump power of this study is shown that the heat transport ability of nanosuspension is 1.5–2 times of water at the same value of pump power.

    There have been conflicting reports as to whether surface wettability is effective in the freezing delay enhancement of attached water droplets. It is an important problem in the development of anti-icing surfaces needed for applications, such as aircraft wings and infrastructures. Here, we prepared precooled ambient conditions and surfaces which included smooth, microstructured, and two nanostructured surfaces with hydrophobic coatings to create an environment closer to the actual environment and to avoid frost formation, which enhances wetting transition and nucleation. Static and dynamic wetting characteristics of each surface were investigated as the fundamental properties and the freezing behavior of precooled water droplets were observed. A distinct elongation of the freezing delay time was observed for droplets on nanostructured surfaces which have static contact angles >150°, in contrast to those on smooth and microstructured surfaces. However, the difference in droplet adhesion induced by nanostructures showed a negligible impact on freezing delay. These results indicated that the reduction of the actual contact area between the solid and liquid phases restricted ice nucleus formation.

Simulations employ a Stefan number Ste = 0.65, Prandtl number Pr = 54, and Rayleigh number covers a range up to 108. The simulations show distinct regimes of the melting process: (i) conductive regime, (ii) stable growth regime, (iii) coarsening regime, (iv) turbulent regime. We show how the solid/liquid interface easily observed in the experiment is enough to identify these regimes and so the internal state of the velocity and temperature fields.

    The hollow inside of a carbon nanotube (CNT) has great potential not only for flow rate enhancement of nanocapillary, but also for a material container which can be applied for drug delivery and nanoparticle infusion. However, these applications focus on after liquid infusion into CNTs, whereas the understanding of the filling process is still limited. We conducted capillary filling experiments using individual open-ended CNTs, which were stuck into an ionic liquid and visualized by scanning transmission electron microscopy. The results showed that the meniscus stopped inside the CNT, which is not predicted by the Lucas-Washburn equation. To explain this discrepancy, the intermolecular force between the liquid and CNT inner wall was proposed to provide an additional friction force. In addition, voids were observed in the liquid inside the CNT. The generation mechanism of voids was proposed to be induced by the instability of the thin liquid layer along the CNT inner surface caused by the advance of the three-phase contact line. The results of the present study increase our understanding of nanoscale capillary action.

    The three-phase contact line (TPCL) motion during evaporation of nanofluid sessile droplet was experimentally investigated to reveal the effect of characteristic surface structure and dimensions of contained materials on evaporation profiles. Nano and microstructured surfaces were prepared through chemical treatment and two sizes of SiO2 spherical particles were used as deposition materials. The contact angle and contact base radius profiles were studied through captured side view images and the sessile droplet method. Discontinuous TPCL motion was observed on micro/nano hierarchical structure, while continuous contact line receding during evaporation was seen on nanostructured surface. In addition, nanofluid with low particle concentration showed large contact angle and contact radius jump relative to dense nanofluid. This finding shows that the increase the amount of deposited materials on the TPCL regions should lead the undeformable liquid-vapor interface, and it showed opposite trend compared to the result reported by flat surface. The result found in this study will help to understand the deposition patterns on the superhydrophobic surface which is an important issue for evaporation-driven supraparticles fabrication.

    Recently, thermal energy transport systems using the flow drag and heat transfer reduction effect have attracted a great deal of interest for reduction of flowing pump power and heat loss. The surfactant is the most important additive for practical use. However, there have been few studies on the flow drag reduction effect of organic brine with surfactant below 0°C. In our previous work, we demonstrated the flow drag and heat transfer reduction effect of some organic brines with the nonionic surfactant, oleyl hydroxyethyl amine oxide (ODEAO). However, the mechanism underlying flow drag reduction of organic brine with surfactant is not fully understood. In addition, it is difficult to apply ODEAO for practical use because it is rare and very expensive. This study was performed to investigate different nonionic surfactants exhibiting flow drag and heat transfer reduction effect of 50 mass% EG solution below 0°C. In this study, a complex of oleyl dimethyl amine oxide (C18DMAO) and o-toluic acid was used as the flow drag surfactant additive. In addition, a vortex inhibition test was performed to determine a suitable molar concentration ratio between C18DMAO and o-toluic acid for 50 mass% EG solution. At this suitable surfactant concentration, dynamic light scattering analysis indicated that the size of rod-like micelles of C18DMAO was in the range of 79 - 142 nm. Finally, the flow drag and heat transfer reduction effect of 50 mass% EG solution with C18DMAO and o-toluic acid were confirmed experimentally at 0°C and -10°C.

    The three-phase contact line motion on a superhydrophobic surface through particle-laden sessile droplet evaporation was investigated. Sample surfaces with micro- and nanoscale structures were generated by various durations of chemical treatment and SiO2 spherical particles with different sizes were used as additives of test liquid. The contact angle and contact radius profiles were studied, and the discontinuous motion of those profiles on micro- and nanostructured hierarchical surfaces was observed, while it was not observed on a nanostructured superhydrophobic surface. Suspensions with low particle concentration induced a relatively large contact radius jump compared to the high-concentrated condition
    in contrast, the previous report showed the opposite trend for flat surfaces. In order to explain this result, a simple explanation was provided - that the stacked particles at the contact line region suppressed to the deformation of the liquid-vapor interface near the contact line. This is confirmed by side-view images of the deposition results because the contact line region after evaporation of the dense suspension showed a large contact angle compared to that of the diluted suspension. In addition, deposition at the contact line region was observed by scanning electron microscopy to discuss the effect of the characteristic length scale of the surface structure and particles on the contact line motion. We believe that these results will help one to understand the deposition phenomenon during particle-laden droplet evaporation on the superhydrophobic surface and its applications such as evaporation-driven materials deposition.

The purpose of this study was to clarify the effects of the basic parameters on the flow characteristics with a cylindrical heater, and to determine available factors to enhance the heat transfer from the horizontal heater. The parameters estimated were the distance between the horizontal heater and the cylindrical heater, and the size and heat flux of each heater. Flow characteristics have three distinct patterns: no reversed flow, reversed flow that reaches the horizontal heater, and reversed flow that does not reach the heater. Heat transfer was enhanced using the cylindrical heater. In the cases of no reversed flow and reversed flow not reaching the horizontal heater, the heat transfer enhancement increased with the modified Rayleigh number of the cylindrical heater. In the range of low numbers, the reversed flow reaching the heater provided heat transfer enhancement.

    Recently, there has been considerable interest in various renewable energies. Among them, solar cell production has increased markedly because the photovoltaic is a clean and safe power generation method. The dye-sensitized solar cell (DSSC) has attracted much attention as an alternative to silicon solar cells due to lower manufacturing costs and plentiful resources for DSSC production. However, the performance of DSSCs has been limited by their durability and low photoelectric conversion efficiency. Temperature control of DSSCs via phase-change materials (PCMs) is expected to improve performance. In this study, DSSCs were heated or cooled with a heat exchanger copper block that was in contact with a PCM (heptadecane), while being irradiated by a solar simulator light source. The durability and photoelectric conversion efficiency of the DSSC improved under PCM temperature control.

    In this study, we investigated the fundamental melting and solidification characteristics of mannitol, erythritol, and their mixture (70 % by mass mannitol: 30 % by mass erythritol) as potential phase-change materials (PCMs) for latent heat thermal energy storage systems, specifically those pertaining to industrial waste heat, having temperatures in the range of 100-250 A degrees C. The melting point of erythritol and mannitol, the melting peak temperature of their mixture, and latent heat were measured using differential scanning calorimetry. The thermal performance of the mannitol mixture was determined during melting and solidification processes, using a heat storage vessel with a pipe heat exchanger. Our results indicated phase-change (fusion) temperatures of 160 A degrees C for mannitol and 113 and 150 A degrees C for the mannitol mixture. Nondimensional correlation equations of the average heat transfer during the solidification process, as well as the temperature and velocity efficiencies of flowing silicon oil in the pipe and the phase-change material (PCM), were derived using several nondimensional parameters.

    This paper deals with the output improvement of heating and cooling cycle by using the work-fluid including phase change material. The experimental study is carried out by heat exchange between work-fluid and heat transfer surface. The work-fluid is flown to a high temperature or a low temperature heat transfer surface from the narrow path. In order to increase the amount of the heat transmission, a trace of Diethylether (boiling point 34.8 degrees C), as a phase change material (PCM), is added to the work-fluid. The parameters of the experiment are additive amount of PCM, the rotational speed of the displacer piston and the temperature of heat transfer surface. It is clarified that the increasing of engine cycle output is brought by the PCM addition. The effect of PCM addition is evaluated by output ratio which is defined from the experimental cycle output data. The requirements for acquiring the increasing effect of output by adding PCM are clarified.

    Recently, latent heat thermal energy storage system has gained attentions in order to utilize the middle temperature factory waste heat (100-200 degrees C). The purpose of this study is to develop heat storage system with a latent heat storage material for using the middle temperature heat. In this study, the direct contact melting and solidification behavior between heat transfer fluid (oil) and erythritol (PCM) were visualized in order to investigate the characteristics of heat storage and release at difference flow rate of oil (1.0-4.0 kg/min) and the effects of perforated partition plate. In this direct contact method, if the packed height of erythritol increases due to porous solidification, erythritol may be flowed out from a vessel with oil. So to control the packed erythritol height, the effect of a perforated partition plate in the vessel was investigated. As a result, it is found that since the bubbles of PCM are broken by the perforated partition plate, it prevents that the solidified height of PCM increases. (C) 2014 Elsevier Ltd.

    A mathematical model for spiral-wound reverse osmosis systems has been established using a porous media approach. Transport processes through membranes were investigated, fully taking account of concentration polarization associated with spiral-wound reverse osmosis desalination systems. A set of the governing equations, namely, the continuity, momentum, and concentration equations, have been derived for three distinctive phases, namely, brine, permeate, and membrane phases, following the procedure previously proposed by Nakayama and Sano for the analysis of hollow-fiber desalination modules. The first-order differential equations in terms of the average velocity, pressure, and salt concentration for the brine phase are integrated with an algebraic equation for the permeate flow rate per unit volume in order to estimate the permeate salinity, flow rate, and pressure drop in spiral-wound reverse osmosis modules. The present analytical results agree fairly well with available experiment data reported by Avlonitis et al. [Desalination, 81: 191, 1991; 86: 273, 1992; 89: 227, 1993; 203: 218, 2007; Sep. Sci. Technol., 40: 2663, 2005], substantiating the validity of the governing equations based on the porous media approach for spiral-wound reverse osmosis systems. The present analysis reveals that there exists an optimal brine pressure for attaining the maximum permeate flow rate for a given pumping power. The present model can be used to design spiral-wound reverse osmosis desalination systems without resorting to extensive finite difference calculations.

    Paraffin is used as a latent heat energy storage material because it has relatively high latent heat and various melting points. However, the low thermal conductivity of paraffin leads to more time in latent heat storage and release processes. Therefore, it is necessary to improve the latent heat storage and release processes of paraffin. It is noted that metal fiber materials are mixed with paraffin in order to enhance the effective thermal conductivity of paraffin. The present investigation experimentally deals with the heat storage and heat release process of paraffin with metal fiber materials as a function of the volumetric fiber fraction and heating temperature. As a result, the heat release characteristic of paraffin with metal fiber materials was improved by enhanced effective thermal conductivity. On the other hand, the heat storage process of paraffin with metal fiber materials was influenced by the natural convection flow, and the heat storage process was not improved because of the interaction between the enhanced effective thermal conductivity and suppression of the natural convection flow by the metal fiber materials.

    The effects of design parameters on natural convection heat transfer from a horizontal heated surface with a heated cylindrical pipe were estimated experimentally. The parameters considered were the heat flux of the horizontal heater and the aspect ratio of the heated cylinder. The flow fields around the horizontal heated surface and the heated cylinder were visualized. The results showed that flow characteristics have three distinctive patterns: non flow reversal, flow reversal occurred only in the heated cylinder and reached to the horizontal heater. The necessary conditions to determine the flow fields were discussed. With decreasing the distance of between the heaters and the aspect ratio of the heated cylinder, the ascending flow velocity in the pipe becomes low and flow reversal occurs. In all flow fields, an increasing in the heat flux of the horizontal heater enhances the heat transfer. In the case of no flow reversal and flow reversal occurred only in the heated cylinder, the heat transfer shows the same tendency and increases with increasing the aspect ratio of the heated cylinder. On the other hand, when flow reversal reaches to the horizontal heater, the heat transfer has a little influence on the heated cylinder conditions. Nusselt number is expressed as a function of the modified Rayleigh number of heaters and the nondimensional height.

    Recently, metal fiber materials were made by laminating metal fibers with a diameter of about 30 μm to 300 μm. Since the almost metal fibers were oriented in the horizontal direction (the major axis of the fiber), these metal fiber materials are estimated to be anisotropic with an effective thermal conductivity. However, there is little quantitative data on the anisotropic effective thermal conductivity of the various kinds of metal fiber materials. The purpose of this study is to investigate the anisotropic effective thermal conductivity of various metal fiber materials experimentally and theoretically. In order to measure the horizontal and vertical effective thermal conductivities of these metal fiber materials, new measurement devices were developed. As a result, it is found that the anisotropic effective thermal conductivity of the various metal fiber materials was confirmed, and the horizontal and vertical effective thermal conductivities of these metal fiber materials depend on the bulk density or porosity, Young's modulus, the fiber length, and fiber diameter. And a dimensionless correlation equation for predicting the vertical and horizontal effective thermal conductivities of the various kinds of metal fiber materials was derived in terms of various dimensionless parameters. © 2011 Springer Science+Business Media, LLC.

    An experimental investigation of connected fluidized beds was conducted to study the sorption and desorption characteristics of a new organic sorbent material (HU720PR) for air conditioning systems. Sorption and desorption performance was evaluated for varying initial fluidized bed heights, sorbent powder circulation rates, and air flow velocities. The results indicated significant improvement in sorption/desorption as the air flow velocity increased. It was found that circulation rate has optimal rate on the humidification. An optimal height for the sorbent powder was identified, based on the operating conditions. Non-dimensional correlation equations were developed to describe the water vapor mass transfer processes during sorption/desorption, in terms of relevant non-dimensional parameters.

    Recently, much attention has been paid to investigate the latent heat storage system. Using of ice heat storage system brings an equalization of electric power demand, because it will solved the electric -power-demand-concentration on day-time of summer by the air conditioning. The flowable latent heat storage material, Oil/Water type emulsion, microencapsulated latent heat material-water mixture or ice slurry, etc., is enable to transport the latent heat in a pipe. The flowable latent heat storage material can realize the pipe size reduction and system efficiency improvement. Supercooling phenomenon of the dispersed latent heat storage material in continuous phase brings the obstruction of latent heat storage. The latent heat storage rates of dispersed water drops in W/O (Water/Oil) emulsion are investigated experimentally in this study. The water drops in emulsion has the diameter within 3 similar to 25 mu m, the averaged water drop diameter is 7.3 mu m and the standard deviation is 2.9 mu m. The direct contact heat exchange method is chosen as the phase change rate evaluation of water drops in W/O emulsion. The supercooled temperature and the cooling rate are set as parameters of this study. The evaluation is performed by comparison between the results of this study and the past research. The obtained experimental result is shown that the 35K or more degree from melting point brings 100% latent heat storage rate of W/O emulsion. It was clarified that the supercooling rate of dispersed water particles in emulsion shows the larger value than that of the bulk water.

    Recently, latent heat thermal energy storage system has been used in order to utilize the middle-temperature (100 - 200 °C ) factory-waste heat. In the range of middle temperature, erythritol is a suitable PCM, which has melting point at 119 °C , and latent heat of 340 kJ ⁄ kg . In this experiment, silicon oil as a heat transfer fluid injects from the nozzle plate of the bottom of a heat storage vessel. It flows to the upper direction through PCM region and heat is directly transfered between PCM and oil. In this study, the melting and solidification behavior between oil and PCM were visualized in order to investigate the characteristics of heat storage and release at difference flow rate of heat transfer fluid (1.0 - 4.0 kg ⁄ min ) and packed height of PCM (0.23, 0.45, 0.60 m ). The experimental result shows that the amount of heat storage and release is influenced by the flow rate of oil and the packed height of PCM. It is found that the volumetric overall heat transfer coefficient increases when the flow rate of the oil increases. During solidification process, the volumetric overall heat transfer coefficient decreases with increasing the packed height of PCM, while, it is not different in the melting process.

    We conducted an experimental investigation of natural convection in an enclosure containing horizontal parallel heated plates. Our experimental setup was as follows: Two heated plates were arranged vertically in an enclosure. The temperature of the ceiling was maintained at a constant low temperature, while the other sides satisfied thermal insulation boundary conditions. We examined flow characteristics in the enclosure and heat transfer around the horizontal heated plates. In the region between the cooled ceiling and the upper heated surface, vortex motion occurred when the accompanying flow from the lower region interfered with the ascending flow. Heat transfer around the heated surface was enhanced by this vortex motion. In other regions, the flow circulated along the heated surfaces in all cases. Generally speaking, for each flow pattern, the Nusselt number was proportional to some power of the modified Rayleigh number. (C) 2012 Elsevier Ltd. All rights reserved.

    A continuous circulating of sorbent powder for sorption and desorption process in two connected fluidized beds has been developed. Two fluidized beds are arranged next to each other and connected by spiral tubes. The experiments were carried out under the various conditions such as air velocity, desorption air temperature, and sorbent powder circulation rate. Sorption and desorption characteristics of sorbent powder of the organic sorption materials show that sorption and desorption performance promoted by increasing air velocity and desorption air temperature. It was found that the spiral revolution speed has optimal value on the humidification. Furthermore, the non-dimensional correlation equations were obtained for water vapor mass transfer under sorption and desorption process in terms of relevant non-dimensional parameters.

    In this paper, the desiccant rotor with double ventilation system is proposed in order to improve the sorption efficiency of the rotor. In this system, the processing air is dehumidified with the rotor. Next, the air becomes high relative humidity by cooling with an air cooler, and it is ventilated to the rotor again for dehumidification. This desiccant rotor with the organic sorbent has high adsorption ability at high relative humidity and can be recovered at low temperature. In this study, ventilation experiments of four types of air flow routes were investigated. In the experiment, temperature and absolute humidity of the air at the entrance and exit of each zone were measured. It is clarified that each route has own characteristics on dehumidification. As a result, it is found the most suitable route of the double ventilation dehumidification system.

    In order to improve the sorption efficiency of the desiccant rotor, double ventilation rotor system has been proposed. In this system, at first the process air is dehumidified in the rotor. Next, the air becomes high relative humidity by cooling with an evaporator, and it is ventilated to the rotor again. In the first report, ventilation experiments of four types of air flow routes were investigated and it is clarified that each route has own characteristics on dehumidification. In this paper, the experiments of double ventilation rotor system of various flow routes were investigated with a refrigerator as a heat pump. Temperature and absolute humidity of the air at the entrance and exit of each zone were measured. Dehumidification amount of the rotor in single ventilation dehumidification system was equal to that in double ventilation dehumidification system. But recovered cold heat from evaporator in double ventilation dehumidification system was higher than that in single ventilation dehumidification system. With increasing the absolute humidity of inlet air, dehumidification amount of the rotor in each route and the absolute humidity of exit air increased. The COP of double ventilation dehumidification system was higher than that of single ventilation dehumidification system.

    Flow drag and heat transfer reduction effects are useful in heat energy transportation systems and can lead to lower pumping energy requirements. The purpose of this research is to describe the flow drag and heat transfer reduction characteristics of organic (potassium acetate) and inorganic (calcium chloride) brine solutions. The nonionic surfactant oleyl dihydroxyethyl amine oxide (ODEAO) is used as a drag-reducing additive. The pipe friction coefficient and heat transfer coefficient are investigated experimentally in a straight pipe for each type of solution with ODEAO. These coefficients are found to be lower than those of water in the turbulent flow range. However, the rod-like micelles of ODEAO, which are necessary to induce the flow drag reduction effect, are not readily formed in these solutions. Hence, the flow drag and heat transfer reduction effects are measured only under limited conditions and it is difficult to apply these solutions practically as heat transfer media.

    The effect of design parameters on natural convection heat transfer from horizontal heated plates in an enclosure is investigated experimentally. Our experimental setup is described as follows: Two heated plates are arranged in the vertical direction. The temperature of the ceiling is maintained at a constant low temperature. The other sides satisfy the thermal insulation boundary condition. To clarify the effects of the design parameters, the relationship of heat transfer to the heat flux and the aspect ratio of the enclosure were examined. The results show that the flow characteristics have two distinctive patterns: one includes vortex motion, and the other comprises a flow along the heated surface. An increase in the heat flux promotes vortex motion and enhances heat transfer. The heat transfer is independent of the height of the adjacent air space. The heat transfer from the heated surface that gives rise to the vortex motion is not influenced by the enclosure diameter, whereas the heat transfer from the other surfaces increase linearly with the enclosure diameter. Nusselt number is expressed as a function of the modified Rayleigh number and the non-dimensional enclosure diameter. © 2011 The Japan Society of Mechanical Engineers.

    In this study, in order to use waste heat in middle temperature region (100℃〜250℃) from factories, it is investigated about fundamental melting characteristic of erythritol, mannitol, and their mixtures as phase change materials (PCMs), which are applicable for latent heat thermal energy system. The melting point of erythritol and mannitol, melting peak temperature of their mixtures, and latent heat were measured by differential scanning calorimetry (DSC). The melting behavior of these PCMs put in the test tube was observed by the digital camera. The acquired conclusions are; 1) In the DSC measurement, it was found that at mannitol content from 10 to 40mass% and from 70 to 90mass%, these mixtures have one and two melting peak temperature, respectively, and at mannitol content from 50 to 65mass%, it have three melting peak temperature. 2) In fundamental melting behavior of mixtures, it was confirmed that the melting behavior with repeated solidification and melting process does not change, and the density difference of solid phase and liquid phase affects the melting behavior.

    In this paper, natural convection in an enclosure which two parallel heated plates are included is investigated experimentally. We consider the experimental model stated as follows : two heated plates arranged in the vertical direction : the surface of heated plates have constant heat flux : the temperature of ceiling is kept for cooling : the other sides have thermal insulation boundary condition. The relevance of the flow in the enclosure and the heat transfer characteristics from each heated surface was presented. In the area of between cooled ceiling and heated surface, vortex motion arises when the ascending flow from the upper plates and the accompanying flow to the rising flow from lower area are interfered. Heat transfer around heated surface is enhanced by the vortex motion. In the other areas, the flow is circulated along the heated surface, and average Nusselt number is proportional to modified Rayleigh number at the power in general.

    The flow drag and heat transfer reduction effect of brine solution is important technology for the effective energy consumption system. A nonionic surfactant (oleyldihydroxyetyl amine oxide) as the flow drag reduction additive was dissolved in an organic brine (propyleneglycol) solution. The pipe friction and heat transfer coefficients of this brine solution have been measured for some experimental parameters. It was found that the flow resistance and heat transfer coefficients of this solution were decreased in the turbulent flow range, but the flow drag and heat transfer reduction tendency was varied with different ranges of the solution temperature.

    An experimental investigation of a fluidized bed with multiple cooling pipes was conducted to study adsorption characteristics of a new organic sorbent desiccant material (HU300P) for a new air conditioning system. The mass ratio of the present sorbent desiccant powder type is from 1.3 to 2.3 times greater than that of silica gel. The sorption rate of the water vapor in the sorbent bed was measured under various conditions. It was found that the sorption rate is highly dependent on the effect of cooling pipes. The sorption ratio increases and the completion time for the sorption process decreases by using multiple cooling pipes.

    This paper describes heat and mass transfer characteristics of organic sorbent coated on heat transfer surface of a fin-tube heat exchanger. The experiments in which the moist air was passed into the heat exchanger coated with sorption material were conducted under various conditions of air flow rate (0.5-1.0 m/s) and the temperature of brine (14-20 degrees C) that was the heat transfer fluid to cool the air flow in the dehumidifying process. It is found that the sorption rate of vapor is affected by the air flow rate and the brine temperature. Meanwhile, the attempt of clarifying the sorption mechanism is also conducted. Finally the average mass transfer coefficient of the organic sorbent coated on heat transfer surface of a fin-tube heat exchanger is non-dimensionalzed as a function of Reynolds number and non-dimensional temperature, and it is found that the effect of non-dimensional temperature on them is larger than Reynolds number .

    This paper describes the transient sorption characteristics of organic sorbent under the low temperature. Our previous research result has shown that the organic sorbent had a large amount of water vapor uptake ability, and was also excellent in processability and deterioration resistance. The measured results of sorption isotherm equilibrium revealed that the organic polymer sorbent was a kind of material which sorption ability depends on temperature. The experiments in which the moist air was passed into the heat exchanger coated with sorption material were conducted under various conditions of the air flow velocity, the brine temperature and the air absolute humidity. It is found that the sorption rate of vapor is affected most greatly by the air absolute humidity. Finally the average mass transfer coefficient of the organic sorbent is non-dimensionalized as a function of Reynolds number, non-dimensional temperature and non-dimensional vapor pressure of saturation.

The organic powder type sorbent made from a bridged complex of sodium polyacrylate which is one of the sorption polymers is adopted in this study. Sorption rate of water vapor and the variation of temperature in the sorbent bed with time were measured under various conditions. As a result, sorption ratio increases and the completion time for the sorption process decreases by using a cooling pipe. Furthermore, the non-dimensional correlation equations were obtained for water vapor mass transfer under sorption process in terms of relevant non-dimensional parameters.

    A two-dimensional numerical simulation of natural convection in a rectangular enclosure heated from below and cooled from above has been conducted with non-Newtonian phase-change-material (PCM) microcapsulate slurry with latent heat capacities. The formulation of the mathematical model in dimensionless co-ordinates and discretization of the governing equations have been done using the finite volume method. Both natural convection and heat transfer characteristics are discussed about natural convection with PCM microcapsulate slurry, which exhibits the pseudoplastic non-Newtonian fluid behavior and a peak value in the specific heat capacity with latent heat. The viscosity of the present PCM microcapsulate slurry is assumed to follow the Ostwald-de Waele power law fluid model with the power-law index n and the consistency coefficient K. The effects of phase-change material, the mass concentration, and the aspect ratio Ar on the natural convection heat transfer are described, respectively. By comparing with the results of microcapsule slurry without phase change, the enhancement in heat transfer is found in microcapsule slurry with phase change during the phase change temperature range. Numerical simulations are performed in the following parametric ranges: the width-height aspect ratio of the enclosure Ar from 2 to 20, the mass concentrations C-m of the slurry from 10 to 40%, power law index n of the slurry from 0.89 to 1.0 and Rayleigh numbers Ra ranges from 10(3) to 10(7).

    The viscous characteristics of ethylene glycol (EG) solution with flow drag reduction additive have been investigated experimentally. In this study, oleyldihydoroxyetyl amineoxide (ODEAO) was used as the flow drag reduction additive, and an aqueous solution of EG was used as a secondary refrigerant. The viscosity of the EG solution with ODEAO was measured with a rotational rheometer. The experimental parameters of viscosity measurement were the temperature of the EG solution with ODEAO, the ODEAO concentration, and the EG concentration. From the experimental results, the apparent viscosity of the EG solution with ODEAO showed SIS (shear induced state). The non-linear dependence of shear stress on shear rate has been well approximated by the power-law model under high shear conditions. The power-law contents, pseudoplastic viscosity, and index number have been estimated for each experimental parameter. Using the measured viscosity and non-dimensional analysis, the flow drag and heat transfer reduction effect of the EG solution with ODEAO has been investigated. © 2006 Wiley Periodicals, Inc.

    Flow drag and heat transfer reduction phenomena of non-ionic aqueous surfactant solutions flowing in helical and straight pipes have been experimentally investigated at surfactant solution concentration range of 250-5000 ppm and temperature range of 5-20 degrees C. The helically coiled pipes have curvature ratios range of 0.018-0.045. Experimental findings indicate that the friction factors and the heat transfer coefficients of the surfactant solution in helical pipes are significantly higher than in a straight pipe and lower than Newtonian fluid flow like water through the same coils in the turbulent drag reduction region. Drag reduction and heat transfer reduction increase with an increase in surfactant solution concentration and temperature in the measured concentration and temperature ranges. On the other hand, they decrease with increasing of the curvature ratio. A set of empirical expressions for predicting the friction factor and the average Nusselt number for the surfactant solution's flow through helical and straight pipes have been regressed based on the obtained data in the present experiments.

    An analytical solution to a composite annular fin made of a substrate metallic fin and a coating layer has been carried out. Useful expressions for calculating temperature distribution and fin efficiency have been derived. Comparing the analytical results to those of numerical calculation, the premise for the expressions is also explored. Theoretical analyzing results show. that fin efficiency of a coated fin decreases with an increase of the coating layer thickness if the thermal conductivity of coating layer is much less than that of the substrate metallic fin. Whereas, the reverse influence of the coating layer thickness on the fin efficiency appears if the thermal conductivity of the coating layer is beyond the above range.

    The reduction characteristic of turbulent drag and heat transfer of drag reduction surfactant solution flowing in a helically coiled pipe were experimentally investigated. The drag reduction surfactant used in the present study was the amine oxide type nonionic surfactant of oleyldihydroxyethylamineoxide (ODEAO, C22H45NO3=371). The zwitterion surfactant of cetyldimethylaminoaciticacidbetaine (CDMB, C20H41NO2=327) was added by 10% to the ODEAO solution in order to avoid the chemical degradation of ODEAO by ionic impurities in a test tape water. The experiments of flow drag and heat transfer reduction were carried out in the helically coiled pipe of coil to pipe diameter ratio of 37.5 and the helically coiled pipe length to pipe diameter of 1180.5 (pipe diameter of 14.4 mm) at various concentrations, temperatures and flow velocities of the ODEAO surfactant solution. The ODEAO solution showed a non-Newtonian behavior at high concentration of the ODEAO. From the experimental results, it was observed that the friction factor of the ODEAO surfactant solution flowing through the coiled pipe was decreased to a great extent in comparison with water as a Newtonian fluid in the turbulent flow region. Heat transfer measurements for water and the ODEAO solution were performed in both laminar and turbulent flow regions under the uniform heat flux boundary condition. The heat transfer coefficients for the ODEAO solution flow were the same as water flow in the laminar region. On the other hand, heat transfer reduction of the ODEAO solution flow was remarkedly reduced as compared with that of the water flow in the turbulent flow region.

    The present paper reviews the technologies on preventing the agglomeration and the growth of ice particles in water with a very small amount of suitable additives. This summarizes studies on the effects of anti-agglomeration of ice particles and suppression of ice growth by using anti-freeze protein and its substitutes or some kinds of surfactants, and on their applications to ice slurry making systems, and to the coupling technology with surfactant drag reduction of ice slurries. These anti-agglomeration additives are found to well disperse ice particles in water at a very low concentration without a serious depression of the equilibrium freezing temperature. This is concluded to improve the ability of ice slurries as a secondary refrigerant. (C) 2004 Elsevier Ltd and IIR. All rights reserved.

Therefore, the non-linear dependence of shear stress on shear rate was well approximated by the Power-law model under the high shear condition, and pseudoplastic viscosity and index number in each experimental parameter were estimated. And the non-dimensional analysis for flow drag and heat transfer reduction effect of EG solution with ODEAO has been investigated by using this approximation.

    The flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants have been investigated from the viewpoint of the effective energy consumption in an industrial cooling system. In this study, Oleyldihy-droxyetyl Amine Oxide (ODEAO) of non-ion surfactant was used as a drag reduction surfactant additive, and Ethylene Glycol (EG) was used as a organic brine. It was found that the viscosity of EG brine with ODEAO had the non-Newtonian behavior. The flow friction coefficient and mean forced convection heat transfer coefficient of the EG brine with ODEAO in a straight pipe were measured for each parameter of concentration of EG, concentration of ODEAO and temperature of the brine with ODEAO. The obtained experimental results indicated that the EG brine with ODEAO exerted an influence on the flow drag and heat transfer reduction.

    The present paper has dealt with the one-sidewall cooling effect of spherical adsorbent particles packed in a rectangular bed on water vapor adsorption characteristics by a 2-dimensional numerical analysis. The analysis model was considered that one-sidewall of a rectangular packed bed with homogeneous spherical silica gel particles was cooled and another walls were adiabatic. The moist air flowed into the rectangular adsorption bed packed with spherical adsorbent particles. Fuji Sylsia silica gel B was selected as a suitable adsorbent with high adsorption ability over high relative humidity. Numerical results revealed the effects of moist air inlet humidity, airflow velocity, size of spherical silica gel particles, width of the rectangular packed bed, and the side-wall cooling temperature on the amount of water vapor adsorption.

    The present study has been performed for obtaining the heat transfer enhancement characteristics of the plural microencapsulated solid-liquid phase change materials (PCM) slurry having different sizes, which flows in a straight tube heated under a constant wall heat flux condition. In the turbulent flow region, the friction factor of the plural PCM slurry was found to be lower than that of pure water flow due to the drag reducing effect of the PCM slurry. The heat transfer coefficient of the plural PCMs slurry flow in the tube was increased by both effects of latent heat evolved in phase change process and microconvection around plural microcapsules with different diameters. The experimental results revealed that the average heat transfer coefficient of the plural PCMs slurry flow was about 2similar to2.8 times greater than that of a single phase of water.

    This paper has dealt with the natural convection heat transfer characteristics of microemulsion slurry composed of water, fine particles of phase change material (PCM) in rectangular enclosures. The microemulsion slurry exhibited non-Newtonian pseudoplastic fluid behavior, and the phase changing process can show dramatically variations in both thermophysical and rheological properties with temperature. The experiments have been carried out separately in three subdivided regions in which the state of PCM in microemulsion is in only solid phase, two phases (coexistence of solid and liquid phases) or only liquid phase. The complicated heat transfer characteristics of natural convection have appeared in the phase changing region. The phase change phenomenon of the PCM enhanced the heat transfer in natural convection, and the Nusselt number was generalized by introducing a modified Stefan number. However, the Nusselt number did not show a linear output with the height of the enclosure, since a top conduction lid or stagnant layer was induced over a certain height of the enclosure. The Nusselt number increased with a decrease in aspect ratio (width/height of the rectangular enclosure) even including the side-wall effect. However, the microemulsion was more viscous while the PCM was in the solid phase, the side-wall effect on heat transfer was greater for the PCM in the solid region than that for the PCM in the liquid region. The correlation generalized for the PCM in a single phase is Nu=1/3(1-C-1)Ra-1/3,Ra-5n+1, where C1=e(-0.09AR) for the PCM in solid phase and C-1 = e(-0.33AR) for the PCM in liquid phase. For the PCM in the phase changing region, the correlation can be expressed as Nu=CRa(1/7n+2)Ste(-(1.9-1.65n)), where C = 1.22 - 0.035AR for AR&gt;10 and C=0.55-16.4e(-1.1AR) for AR&lt;10. The enclosure height used in the present experiments was varied from H=5.5 [mm] to 30.4 [mm] at the fixed width W=120 [mm] and depth D=120 [mm]. The experiments were done in the range of modified Rayleigh number 7.0x10(2)less than or equal toRaless than or equal to3.0x10(6), while the enclosure aspect ratio AR varied from 3.9 to 21.8.

    In the present experimental study, the stability of Rayleigh-Bernard convection has been investigated in rectangular enclosures filled with microemulsion Phase-Change-Material (PCM) slurry. The PCM slurry exhibited a pseudoplastic non-Newtonian fluid behavior. Hysteresis in convection was clearly observed while the PCM were in a solid phase and in phase changing. The critical Rayleigh number decreases with the PCM mass concentration while the PCM is in phase changing. The fluid temperature at the center of the enclosure showed a time-dependent oscillation during the transition from a heat conduction state to a convection state. The maximum Nusselt number has been observed for all of the slurries while the heating plate was controlled at a temperature that most of PCM was in phase changing.

    Recently, studies have begun on a functional heat transfer medium using fine spherical microcapsules encapsulated with phase-change material and dispersed in water. This enables the medium to maintain fluidity whether the phase-change material is solid or liquid. The present study has clarified the laten-heat storage characteristics of microcapsule slurry by increasing its heat transfer coefficient with the help of evolved heat condensing of vapor from the slurry in heat storage. Paraffin wax with the melting point of 62°C was encapsulated into the fine microcapsules and used as a phase-change material. The cooling coil surface temperature and concentration of paraffin in the microcapsule slurry were selected as the experimental parameters. As a result, the non-dimensional correlation equations of the heat release completion time and heat transfer coefficient were derived in terms of non-dimensional parameters.

A rectangular cavity with a heating vertical wall, which was filled with the microcapsule slurry, was selected as the present research model. The heating wall temperature, the width of the cavity and the PCM concentration were set as parameters. It was clarified that the transportation of latent heat evolved by melting of the PCM in the slurry exerted on a remarkable influence on the natural convection heat transfer. In addition, it was found that the heat transfer coefficient reached a local maximum value with an increase in initial temperature difference between heating wall and PCM. The heat storage completion time also have a local maximum value with an increase in heating wall temperature due to the latent heat by melting the PCM in the slurry.

    An experimental study has been conducted in dealing with natural convection heat transfer characteristics of microemulsion slurry in rectangular enclosures. The microemulsion slurry used in the present experiment was composed of water, surfactant, and fine particles of phase-change-material (PCM). The PCM mass concentration of the microemulsion slurry was varied from a maximum 30 mass% to a diluted minimum 5 mass%, and the experiments have been done separately in three subdivided temperature ranges of the dispersed PCM particles in a solid phase, two phases (coexistence of solid and liquid) and a liquid phase. The results showed that the Nusselt number increased slightly with the PCM mass concentration for the slurry in solid phase. In the phase change temperature range, the Nusselt number increased with an increase in PCM mass concentration of the slurry at low Rayleigh numbers, while it decreased with increasing PCM mass concentration of the slurry at high Rayleigh numbers. There was not much difference in natural heat transfer characteristics of the PCM slurry with low PCM concentrations(&lt;10 mass%), however, the difference was getting greater with increasing the PCM concentration, especially for the enclosure at a lower aspect ratio (width/height of the rectangular enclosure). The enclosure height was varied from 5.5 to 24.6 mm under a fixed width and depth of 120 mm. Hence, the experiments were performed for a wide range of modified Rayleigh number from 3x10(2) to 1.0x10(7). The correlation generalized for the PCM slurry in a single phase was derived in the form of Nu=0.22(1-C(1)C(m)e(-C 2 AR))Ra1/(3n+1), where C-1 and C-2 were the optimum fitting constants obtained by the least square method. While the PCM was in a phase changing region, the correlation could be expressed as Nu=0.22(1-C(1)C(m)e(-C 2 AR))Ra1/(3n+1) Ste(-0.25), where the Ste was the modified Stefan number.

    A two-dimensional numerical study has been conducted to obtain fluid flow and heat transfer characteristics for Rayleigh-Benard natural convection of non-Newtonian phase-change-material (PCM) slurries in a rectangular enclosure with isothermal horizontal plates and adiabatic lateral walls. Generally, with the melting of PCM, the slurry's density draws down sharply but continuously and the slurry's specific heat capacity shows a peak value. Some PCM slurries such as microemulsions can exhibit pseudoplastic non-Newtonian fluid behavior. This paper deals with the differences in natural convection and flow patterns between Newtonian and non-Newtonian fluids with or without PCM theoretically. Due to the participation of PCM in natural convection, the dependency of Rayleigh number Ra alone cannot reflect its intensity that a modified Stefan number has to be taken into account. A correlation is generalized in the form of Nu = C . Ra-l . Ste(-m) which has a mean deviation of 10.4% in agreement with the calculated data. The numerical simulation has been performed with the following parameters: a shear thinning pseudoplastic fluid for pseudoplastic index 0.8 less than or equal to n less than or equal to 1.0, 6 x 10(3) less than or equal to Ra less than or equal to 2 x 10(6), Prandtl number Pr = 70-288, and the aspect ratio of the rectangular enclosure from 10 : 1 to 20 : 1.

    This paper has dealt with the natural convection heat transfer of the microcapsule slurry composed of phase change material (PCM) as a latent heat storage substance. A rectangular cavity with two opposing heating and cooling vertical walls was selected as the present research model. The temperature difference between heating and cooling walls, the width of the cavity and the PCM concentration were set as parameters of natural convection heat transfer. The heat transfer coefficient of heating and cooling wall, the flow velocity profile and the temperature distribution of the microcapsule slurry were calculated by numerical computation. It was clarified that the transportation of latent heat evolved by melting and solidifying of the PCM in the slurry exerted on a strong influence on the natural convection heat transfer. Moreover, it was found that the heat transfer coefficient reached at the local maximal value with an increase in temperature difference between heating and cooling walls. In addition, Nusselt number was influenced by the transportation effect of latent heat that was caused by melting and solidifying of the PCM. The numerical results revealed quantitatively that the natural convection heat transfer depended on the PCM concentration, temperature difference between heating and cooling walls, and width of the rectangular cavity.

    The present experiment and numerical analyses have been performed for obtaining the cold heat storage characteristics of a water mixture of microcapsules packed with liquid-solid phase change material (PCM) flowing in a pipe cooled under the constant temperature wall condition. The energy equation was formulated by taking into consideration of the heat release due to the PCM solidification process and the heat transfer enhancement induced by the microconvection of microcapsules. The heat source function in the energy equation was derived from solutions for the solidification in a spherical latent heat material. The governing parameters were found to be latent heat material concentration, cooling wall temperature, microcapsule diameter and velocity of water mixture of the microcapsules. The experimental and numerical results revealed that mean heat transfer coefficient for the water mixture of the latent microcapsules was about 1.6∼2.5 times greater than that for the single phase of water.

    This paper has dealt with the heat transfer enhancement of flowing water with flow drag reduction additive into a heat transfer tube by inserting wire coils. The non-ion type surfactant was used as the additive to decrease the pipe flow resistance for the heat energy transport system. However, the decrease in the flow resistance was allowed to reduce the heat transfer coefficient in the heat transfer tube. Some kinds of wire coils having different diameters were tried to enhance the heat transfer in the heat transfer tube. The effects of wire coils on the pipe friction and the heat transfer coefficients were elucidated under various experimental parameters of flow velocity, wire coil diameter, pitch and length.

    The present numerical analysis has been performed for obtaining the heat transfer characteristics of microencapsulated solid-liquid phase change material and water mixed slurry flow in a circular tube heated with constant wall heat flux. The energy equation was formulated by taking into consideration of the heat sink due to melting process and the heat transfer enhancement induced by the motion of microcapsules. The heat source function in the energy equation was derived from solutions for melting in a spherical latent heat material. The governing parameters were found to be latent heat material concentration, pipe diameter, microcapsule diameter, heat flux, and the slurry velocity. The numerical results revealed that mean heat transfer coefficient for latent microcapsule slurry was about 1.3∼1.8 times greater than that for the single phase of water.

    This paper has concerned preventing snow accumulating upon inclined substrates using falling water film. A cluster of physical models for a gas-water-snow system was developed and solved with a control-volume finite-difference procedure. The effects of various parameters on heat transfer and water film temperature decrease were investigated. The results revealed that it is feasible to use falling water film to prevent snow accumulation upon inclined substrates as long as the suitable initial film flow rate and temperature are adopted. It was clarified that among the influential factors of water film temperature decrease, the snowfall intensity, initial water film thickness and the substrate inclination play an important role. The intensity of the film temperature decrease mainly depends on the snowfall intensity and the initial heat capacity of the water film flow, which is a function of temperature and mass flow rate. An intensive heat transfer occurs in a very thin layer near the free surface of the water film. The numerical results were correlated in terms of effective Nusselt number, and Reynolds, Prandtl and Gukhman numbers. The maximum deviation of the numerical data from the correlation is approximately 15.6%, which only causes an uncertainty less than 3% in the simple prediction.

The effects of various environmental and geometric conditions on energy absorption for the collector were investigated. The results predict collector could obtain the highest solar energy absorptance. The latent heat pur of water evaporation can be 3 to 15 times larger than the sensible heat flux under normal operating conditions. The wind speed and the inlet water temperature have a large influence on the energy absorption of the collector The effects of the solar incident flux, the atmospheric humidity and temperature, the absorbing plate tilt angle and length, and the water film thickness on the temperature rise of the water film and/or the absorptance of the collector are clarified. The open-type flat-plate collector is suitable to operate at lower inlet water temperatures and in regions where the local latitude is in the range of 20 degreesN-40 degreesN, and the weather is humid and hot with low winds.

    It has been well known that some kinds of surfactants are useful to reduce flow drag in a turbulent pipe flow by Toms effect. However, it is expensive to make these surfactants harmless to the environment. On the other hand, the fibrous material such as pulp fibers and cellulose are harmless additives to the environment. This paper deals with the drag reduction and heat transfer characteristics of the water suspension flow mixed with fine fibers in a circular straight pipe. Measurements of velocity and temperature profiles in a circular pipe were made in order to examine the flow drag and heat transfer characteristics of the turbulent and laminar flow. The nondimensional correlation equations of pipe flow resistance and heat transfer were derived in terms of various nondimensional parameters.

    The effects of various parameters on the limiting characteristics of an open-type water-cooled flat-plate collector were studied numerically. The results showed that the heat and mass transfer was enhanced with an increase in the inlet water temperature. The operating temperature and the interfacial mass flux maintained a higher constant for 4 and 2 hours around the noontime, respectively. An increase in atmospheric temperature or humidity and a decrease in the film thickness caused the operating temperature to rise to some extent. The wind velocity exerted a great influence on the operating temperature.

    This paper has investigated the heat, mass and momentum transfer of a water film falling over a tilted plate with solar radiant heating and water evaporation. A cluster of physical models which include conduction, convection with flow turbulence, diffusion, radiation and phase change was developed for predicting the characteristics of heat, mass and momentum transfer. A fully implicit control-volume finite-difference procedure was used to solve the coupling equations. The effects of various parameters on heat, mass and momentum transport were investigated. The results revealed that the gradients of temperature and the mass fraction of water vapor in the gas layer, and the wind velocity played a key role in the heat and mass transfer along the gas-water interface. The water film Reynolds number related to the film thickness and the plate tilt angle markedly exerted an influence on the eddy viscosity and the turbulent Prandtl number of the water film. The ambient atmospheric temperature only dramatically affected the interfacial sensible heat transfer. The magnitude of solar incident flux had intense influence on the water film temperature but not on the interfacial heat and mass transfers. (C) Elsevier, Paris.

    This paper has concerned the heat and mass transfer of a water film falling down a tilted plate with radiant heating and water evaporation. A cluster of physical models was developed for evaluating the properties of heat and mass transfer. A fully implicit control-volume finite-difference procedure was used to solve the coupling equations. The effects of various parameters on heat and mass transfer were investigated. The results showed that the mass fraction of water vapor in ambient atmosphere and the flow turbulence played key roles in the heat and mass transfer. The ambient atmospheric temperature dramatically affected the sensible heat flux. However its effect on the latent heat flux is negligibly small. The magnitude of solar incident flux had an intense influence on the water film temperature.

    Transient heat release characteristics of a latent heat storage vessel packed with surface cross-linked form stabilized high-density polyethylene pellets as a phase change material (PCM) have been investigated numerically and experimentally. The obtained results revealed the effects of the inlet velocity, the inlet temperature of ethylene glycol/water solution as a heat transfer medium, and the amount of the PCM on the heat release characteristics. As a result, the nondimensional correlation equation of the completion time of the heat release process was derived as a function of some nondimensional parameters.

    Preventing snow buildup on an inclined roof using a falling water film is studied in this paper. A cluster of physical models for a gas-water-snow system has been developed and solved with a fully implicit control-volume finite-difference procedure. The contact flow pattern of a turbulent water film and a laminar gas stream was used in the simulation. The temperatures of the ambient saturated atmosphere and the falling snow were assumed to be equal and below zero Celsius. The outlet temperature of the water film was set at zero Celsius for the critical state. The effects of various parameters on heat transfer and water film temperature drop were investigated. The results revealed that it is feasible to use a falling water film to prevent snow buildup on an inclined roof. It was clarified numerically that among the factors influencing water film temperature drop, the snowfall intensity, the water film flow rate, the roof length and inclination play important roles. Of course the ambient temperature and wind speed also contribute to the water film temperature drop. The critical states of the inlet temperature and flow rate of the water film for various parameters were calculated in the present paper. The intensive heat transfer occurs in a very thin layer near the free surface of the water film in response to snow melting at the gas-water interface. The numerical results were correlated in terms of effective Nusselt number, and Reynolds number, Prandtl number and Gukhman number for simplified predicting. The maximum deviation of the numerical data from the regression line is approximately 15.6%, which causes an uncertainty of less than 3% in simple prediction.

    This paper has dealt with liquid-liquid direct contact heat transfer characteristics by means of water insoluble heat transfer medium. In the present study, Perfluorocarbon(PFC, density of 1830kg/m3)was injected from above into a hot water layer, which was mounted by stainless steel wire net in order to make PFC droplets finer. The measuring result of the drop let diameter revealed that the droplet size distribution exerted an influence on the temperature effectiveness between PFC droplets and the hot water layer. It was observed that PFC droplets were dispersed by collision with stainless steel wire nets during falling in the hot water layer. Finally correlations equations of the temperature effectiveness and average diameter of PFC droplets had been derived as a function of some parameters.

    An experimental investigation was performed to determine the transient desorption characteristics of a fibrous type organic adsorbent, which was composed of the bridged complex of sodium polyacrylate as a new kind of adsorbent. The test fibrous adsorbent was packed in a cylindrical vessel, and dry air was passed through it. The experiments were conducted under various conditions of air velocity, temperature, relative humidity and vessel length. As a result, the pressure loss for the packed bed of the test fibrous adsorbent showed a similar tendency to that for the packed bed of spherical particles. The mass transfer data was correlatd by the modified Sherwood number, the Reynolds number, the Schmidt number, the ratio of desorbed water vapor mass to fibrous adsorbent mass, the nondimensional temperature and the ratio of vessel length to vessel length to fiber diamenter. Fourier number for the complection times of adsorption processes were also correlated by Reynolds number, and the ratio of desorbed water vapor mass to fibrous adsorbent mass, the nondimensional temperature and the ratio of vessel length to fiber diameter.

    Experiment has been performed of heat transfer characteristics of the middle temperature latent heat storage system of the direct-contact heat transfer by using m-E (meso-Erythritol, melting point of 119°C, latent heat of 375 kj/kg) droplets as a latent heat storage material and silicone oil as a heat transfer medium. In the present study the liquid m-E was injected into the heat tranfer medium through a circular nozzle. The m-E droplets changed from liquid to solid phase during falling in the heat transfer medium at low temperature. From the measuring results of m-E droplet diameter, falling velocity, and solidification rate, the nondimensional empirical equations of the arithmetic mean diameter of the droplets and falling velocity, the solidification rate and the overall heat transfer coefficient were derived as a function of the characteristic arithmetic mean diameter, the terminal velocity, temperature and physical properties.

    The present study deals with the heat storage characteristics of the inclined rectangular vessel packed with spape-stabilized paraffin plates as a latent heat storage material by numerical analysis. It was found that the heat storage characteristics were remarkedly affected by the inclination angle of the rectangular vessel and the heat transfer medium flow direction, due to the presence of natural convection in the fluid flow channel between the paraffin plates. Numerical results revealed flow patterns, temperature profiles and heat storage characteristics for various inclination angles, inlet velocities and temperatures of the heat transfer medium fluid, and widths of the fluid flow channel.

    This paper deals with the heat transfer characteristics of a liquid-liquid direct contact operation in which a Perfluorocarbon (PFC) liquid is released in a hot water stream, a low-grade heat source such as urban sewage, for the purpose of heat recovery from it. The paper reports on a set of experiments in which a PFC liquid (1800 kg/m^3 at 20℃) was continuously injected from a single, downward-facing nozzle into a slow, upward flow of hot water to be disintegrated into droplets descending in, and thereby heated from the water flow. The results of the experiments show how the size distribution and the translational motions of the droplets affect the overall coefficient for the water-flow-to-droplets heat transfer and also the temperature effectiveness for the droplets.

    This paper deals with the transient heat storage characteristics of high-density polyethylene pellets used as a latent heat storage material by the condensed heat from the ethylene glycol vapor. The polyethylene pellets are fabricated by the shape-stabilization treatment in which the molten pellets maintain the same shape as the solidified ones. The polyethylene pellets packed in the cylindrical heat storage vessel are melted by the condensed heat from the flowing vapor. The effects of vapor temperature, flow rate and the amount of the pellets on the latent heat storage characteristics are investigated experimentally. Moreover, the vapor movement among the packed pellets is enhanced by using the partition plate in the pellets layer. The nondimensional correlation equations of the completion time of heat storage are defined in terms of various nondimensional parameters.

    This paper has dealt with melting heat transfer characteristics of ice water slurry in an inside tube of horizontal double tube heat exchanger in which a hot water circulated in an annular gap between the inside and outside tubes. Two kinds of heat exchangers were used; one is made of acrylic resin tube for flow visualization and the other is made of stainless steel tube for melting heat transfer measurement. The result of flow visualization revealed that ice particles flowed along the top of inside tube in the ranges of small ice packing factor and low ice water slurry velocity, while ice particles diffused into the whole of tube and flowed like a plug built up by ice particles for large ice packing factor and high velocity. Moreover, it was found that the flowing ice plug was separated into numbers of small ice clusters by melting phenomenon. Experiments of melting heat transfer were carried out under some parameters of ice packing factor, ice water slurry flow rate and hot water temperature. Consequently, the correlation equation of melting heat transfer was derived as a function of those experimental parameters.

    An experimental study was made of the forced convection freezing characteristics on the convex wall of a return bend with a rectangular cross section. Observations were carried out for duct heights of 17 and 30 mm, a duct width of 300 mm, and a radius of curvature of 159 mm. The convex wall temperature was uniformly maintained below the freezing temperature of water, and the concave wall was insulated. It was found that a stepwise ice layer forms on the convex wall of a return bend and that the step position at the steady-state condition is closely dependent on both the water flow velocity and the cooling temperature ratio.

    Experiments have been performed to investigate the freezing heat transfer characteristics in a return bend with a rectangular cross section. The experiments were carried out for two kinds of duct heights of 30 and 50 mm under the fixed size of 300 mm in duct width and 159 mm in curvature radius of convex wall. Both the convex and concave walls of a return bend were kept less than the freezing temperature of water. It was found that the freezing characteristics on the convex wall are markedly different from those on the concave wall of a return bend, and that the cooling temperature ratio is one of the most important parameters on the forced-convection freezing heat transfer in a return bend.

    Experiments have been performed to investigate the freezing heat transfer characteristics in a return bend with a rectangular cross section. The experiments were carried out for two kinds of duct heights of 30 and 50 mm under the fixed size of 300 mm in duct width and 159 mm in curvature radius of convex wall. Both the convex and concave walls of a return bend were kept less than the freezing temperature of water. It was found that the freezing characteristics on the convex wall are markedly different from those on the concave wall of a return bend, and that the cooling temperature ratio is one of the most important parameters on the forced-convection freezing heat transfer in a return bend. © 1995 Springer-Verlag.

    An experimental study of the transient solidification of an aqueous binary solution from a vertical cooled plate is reported in this paper. A copper plate of the flow duct, which has 50 mm x 70 mm in cross-sectional dimension and 500 mm in length, was cooled uniformly. Ethylene-glycol solution was adopted as a testing liquid. The dependence of the plate wall temperature, the flow rate, the entry-liquid concentration, and the entry-liquid temperature on the solidification characteristics were extensively determined. The data reveal that the characteristics of the frozen layer at both the onset and the steady state could be favorably classified as a function of Reynolds number and the cooling temperature ratio. The correlation of the averaged frozen-layer thickness at the steady state was determined.

    An experimental study has been performed to investigate the freezing characteristics of an aqueous binary solution droplet on a cooled wall. Pure water, ethylene-glycol aqueous solutions of 1to 10 mass%, and NaCl aqueous solutions of 1 to 15 mass% in concentration were adopted as the testing solutions. The droplet was frozen under a variety of cooling conditions such as wall temperature, air temperature, air velocity, and solute concentration in both the static atmosphere and the cold air flow. The observations on both the freezing characteristics and the morphologies of the droplet were extensively carried out. In addition, the inside flow of the droplets were observed. It was found that the morphology of the droplet on the cooled wall varied markedly depending on the solution, which appears to be mainly caused by the difference in the surface tension of the solution. On the other hand, under the conditions with a cold air flow, initial freezing point of the droplet was found to be mainly owing to the cooling rate between the cooled wall and the cold air.

    Melting points of some kinds of molten salts have been determined, and also supercooling characteristics of potassium thiocyanate KSCN and calcium chloride CaCl2 have been investigated. Molten salt has been utilized as a thermal storage material, cooling material for the nuclear reactor, refinement of the petroleum, fuel battery, molten-salt reactor because of its excellent thermal characteristics and chemical stability. Therefore, it is important for its utilization to store the data of thermophysical properties to control both the melting and solidification processes. The sample of molten salt is both heated and cooled depending on the prescribed heating-cooling temperature curves in the electric furnace with a controller. The melting points were determined as the constant temperatures which can be observed for some period in the cooling process. Furthermore, the supercooling characteristics were investigated under various sample masses and cooling rates as parameters. It was found that the degree of supercooling depended closely on both the cooling rate and the sample mass.

    Measurements of both the velocity and turbulence-intensity distributions above an ice-layer surface along flow direction have been performed to clarify the ice-layer transition phenomena observed in a rectangular duct. The test duct which has a lower cooled wall kept less than the freezing temperature of water with cross-sectional dimension of 50 mm by 19 mm was used in the present measurements. The velocity and turbulence-intensity distributions in the test duct were measured using Laser Doppler Velocimeter set up on the two-dimensional traversing table. The freezing experiments were carried out under the condition of uniform water-flow rate even after the ice layer has developed in the test duct. It was found that inlet water flow tended to be laminarized under an influence of developing ice layer, and that onset of the ice-layer transition phenomena might be closely related to an increase in turbulence intensity in the water flow above the developing ice-layer surface.

    An experimental study has been performed to investigate the freezing behavior on the convex wall of a return bend with a rectangular cross section. The experiments were carried out for the duct heights of 17mm and 30mm with a duct width of 300mm and a radius of curvature of 159mm. The convex wall temperature was uniformly maintained below the freezing temperature of water, while the concave wall was insulated. It was found that step wise ice formation was observed on the convex wall of the return bend and that the step position at the steady-state condition was closely dependent on both the water-flow velocity and the cooling-temperature ratio.

    Experimental investigations for sorption and desorption behaviors in a circular-tube fluidized bed were carried out using organic sorbent particles for the development of a desiccant air conditioning system. Mixing of the fluidized bed intensified with increasing velocity of the air flow passing through sorbent particles. The effective mass transfer coefficient increased with increasing air flow velocity. Additionally, a dehumidifying system of circulating fluidized beds with sorbent particles circulated by air flow was created to perform continuous dehumidification. Experiments were conducted to grasp the continuous dehumidification characteristics of the sorbent particles, and the dehumidification behavior was evaluated according to the sorption and desorption amount.

    Electrodialysis using ion-exchange membranes is a means of producing dilute and condensate under the influence of an applied electric potential difference of saltwater. In this study, we have investigated the transport process of ions in the electrodialysis stack under the influence of an applied electric field. Under a limiting current density, the ion concentration totally vanishes at the exit of the diluate channel so that the electric resistance goes infinity toward the diluate side of the cation exchange membrane, which is referred to as concentration polarization. The effect of the flow field on this limiting current density, which is one of the most important design parameters in the electrodialysis stacks, have been investigated by measurement of the electric resistance and concentration.

    The heat transfer of natural convection from upward facing-horizontal heated surface which a heated annular duct was placed above was investigated experimentally. The relationship of the heat transfer to the distance of between the horizontal heated surface and the heated ducts was examined. The flow fields around the heated surface and heated ducts were visualized. With decreasing the distance, the ascending flow velocity in the heated ducts becomes low and the reverse flow occurs. The heat transfer increases with decreasing the distance. Inserting a heated inner duct enhances the heat transfer.

    The purpose of this research is phase change characteristic evaluation of the nanosuspension type heat storage as latent heat material. The target heat storage zone of this study is 50-100℃ as for using of hot spring heat or factory exhaust heat. Tetracosane (50.6℃ of melting point) is used for dispersion material as a latent heat storage material of a nanosuspension. Tetracosane in the nanosuspension is dispersed by about 200 nanometers of average particle diameter in continuous water phase. A latent heat storage material is dispersed by using an ultrasonic homogenizer. This paper deals with the phase change characteristics that estimated by using differential scanning calorimeter. The heating rate and the composition of tetracosane are chosen as experimental parameter.

    Recently, there are a few studies of the engineering properties of the aqueous suspension of nano particles (whose diameter is less than 1 μm). The purpose of this study was to investigate the freezing behavior and freeze concentration of the aqueous suspension of nano or micro silica particles. It was confirmed that the average supercooling degree of the aqueous suspension of nano and micro particles decreased with increasing mean particle diameter. The ice crystal grain of aqueous suspension of micro particles by a polarization microscope observation was smaller than that of nano particles at low cooling rate. From the progressive freeze-concentration technology, it was found that the freeze concentration ratio of aqueous suspension of micro and nano particles increased as the freezing percentage increases in the agitating condition, but there was no freeze concentration of aqueous suspension of micro or nano particles in non-agitating condition because of the particle precipitation or the high cooling rate. It was observed that there was no difference of the freeze concentration ratio in case of an increase of particle diameter. In addition, it was noticed that the freeze concentration ratio decreased in decreasing the agitating rotation and increasing the initial concentration of aqueous suspension.

    The purpose of this study is to develop the latent heat storage system using erythritol as a latent heat storage material. In this study, the direct contact melting and solidification behaviors of erythritol were visualized in order to investigate the characteristics of direct contact heat storage and release between oil and erythritol. In this direct contact method, if the packed height of erythritol increases, erythritol may be flowed out from a vessel with oil. So to control the packed erythritol height, the effect of a perforated aluminum lattice in the vessel was investigated. The experimental results show that the increase of erythritol bubbles was inhibited by the perforated aluminum lattice. And it is found that the amount of heat release is influenced by the form of perforated aluminum lattices.

    In order to improve the sorption efficiency of the desiccant rotor, double ventilation rotor system has been proposed. In this system, at first the process air is dehumidified in the rotor. Next, the air becomes high relative humidity by cooling with an evaporator, and it is ventilated to the rotor again. In the first report, ventilation experiments of four types of air flow routes were investigated and it is clarified that each route has own characteristics on dehumidification. In this paper, the experiments of double ventilation rotor system of various flow routes were investigated with a refrigerator as a heat pump. Temperature and absolute humidity of the air at the entrance and exit of each zone were measured. Dehumidification amount of the rotor in single ventilation dehumidification system was equal to that in double ventilation dehumidification system. But recovered cold heat from evaporator in double ventilation dehumidification system was higher than that in single ventilation dehumidification system. With increasing the absolute humidity of inlet air, dehumidification amount of the rotor in each route and the absolute humidity of exit air increased. The COP of double ventilation dehumidification system was higher than that of single ventilation dehumidification system.

    This paper describes the effect of design parameters on natural convection from horizontal heated plates in an enclosure. The effects of the heat generation and the enclosure height were examined experimentally. The results show that flow characteristics have two distinctive patterns. One includes vortex motion. The other is circulated along the heated surface. The increase of the heat generation develops the vortex motion and enhances the heat transfer. The heat transfer is independent of the height of adjacent air space. In all the heated surfaces, average Nusselt number is related to modified Rayleigh number.

    Desiccant air-conditioning system is a promising technology because the exhaust heat can be effectively used in the future. We have reported the proposed system that combines a desiccant rotor with a vapor compression refrigerator. The confirmation experiment of stability and the performance was conducted with the experimental prototype. The result showed that it had the performance that was necessary for dehumidification driving in the summer and the humidification driving in the winter. In this report, we examined the influence on humidity controlling performance of the processing air temperature and humidity. As a result, we got high dehumidification efficiency and clarified the dehumidification characteristic in dehumidification driving in the summer. Dehumidification efficiency about 4.0 kg/kWh and COP of the system about 2.0 in summer driving mode were obtained.

    There has been some interest in the flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants in order to achieve the effective energy consumption in an industrial cooling system. Therefore, there have been our previous investigations of brine flow (Ethylene Glycol (EG) solution for organic brine) with drag reduction surfactant (Oleyldihydroxyetyl Amine Oxide (ODEAO) of non-ion surfactant) showing the flow drag and heat transfer reduction effect. But some technical issues are that EG is an environmentally harmful brine and the use of EG will be restricted in the future. Whereas, Propylene Glycol (PG) and Potassium Acetate (=PA) are expected to be environmentally friendly brines. But, there have been few studies on the flow drag and heat transfer reduction effects of PG or PA solution with drag reduction surfactants. This present paper shows that the flow friction coefficient and mean forced convection heat transfer coefficient of the PG, or PA solution with ODEAO in a straight pipe were measured for each parameter of concentration of brines, concentration of ODEAO and temperature of the brine with ODEAO. Finally, useful non-dimensional correlative equations for maximum flow resistance and heat transfer reduction effect are derived in terms of various non-dimensional parameters, and these experimental results of PG solution with ODEAO were compared with that of EG solution with ODEAO.

    This paper describes sorption characteristics of organic sorbent coated on heat transfer surface of a plate-fin-tube heat exchanger. The organic sorbent is a bridged complex of soldium polyacrylate. This bridged complex containing the carboxyl group as water vapor adsorption site has a larger adsorption abilities as compared with silica gel. The experiments in which the moist air was passed into the heat exchanger coated with sorption material were conducted under various conditions of air flow rate and the temperature of brine that was the heat transfer fluid to cool the air flow in the dehumidifying process. It is found that the sorption rate of vapor is affected by the air flow rate and the brine temperature. Meanwhile, the attempt of clarifying the sorption mechanism is also conducted. Finally the average mass transfer coefficient of the organic sorbent was non-dimensionalized as a function of Reynolds number and non-dimensional temperature. In addition, it was observed that the factor which affects the sorption rate in the water vapor sorption process of the organic sorbent coated on the heat exchanger shifts from the &ldquo;adsorption step&rdquo; to the &ldquo;sorption step&rdquo;.

    The turbulent flow drag and heat transfer coefficients can be reduced dramatically by adding small amounts of drag-reducing additive to flowing water. The surfactant solutions including rod-like and cord-like micelles shows the Non-Newton characteristics and the flow drag reduction effect in a turbulent pipe flow. In this study, TOHO-DRC6B (main component: Oleyl Dihydoroxy Ethyl Amine Oxide, ODEAO, non-ionic surfactant) was selected as the flow drag reduction additive. ODEAO is added to propylene glycol (PG) solution. From the flow resistance and heat transfer experiment results, the flow resistance and heat transfer coefficient of the PG solution with ODEAO in straight circle pipe were markedly reduced as compared with that of propylene glycol solution as solvents.

    The present study has been performed for obtaining the heat transfer enhancement characteristics of the plural microencapsulated solid-liquid phase change materials (PCM) slurry having different sizes, which flows in a straight tube heated under a constant wall heat flux condition. In the turbulent flow region, the friction factor of the plural PCM slurry was found to be lower than that of pure water flow due to the drag reducing effect of the PCM slurry. The heat transfer coefficient of the plural PCMs slurry flow in the tube was increased by both effects of latent heat evolved in phase change process and micro-convection around plural microcapsules with different diameters. The experimental results revealed that the average heat transfer coefficient of the plural PCMs slurry flow was about 2-2.8 times greater than that of a single phase of water.

    A two-dimensional numerical simulation of Rayleigh-Benard convection in a rectangular enclosure heated from below and cooled from above has been conducted with non-Newtonian phase-change-material (PCM) microcapsulate slurries with latent heat capacities. The formulation of the mathematical model in dimensionless co-ordinates and discretization of the governing equations has been done using the finite volume method. Both flow and heat transfer characteristics are discussed about Rayleigh-Benard natural convection with PCM microcapsulate slurry, which exhibits pseudoplastic non-Newtonian fluid behavior and a peak value in the specific heat capacity. The viscosity of the present PCM microcapsulate slurry is assumed to follow the Ostwald-de Waele power law fluid model with the power-law index n and the consistency coefficient K. The effects of the mass concentration and the aspect ratio Ar on the natural convection are described respectively.

    The flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants have been investigated in order to conserve the energy in a district heating and cooling system. In this study, Ethylene Glycol (EG) solution with Oleyldihydroxyetyl Amine Oxide (ODEAO) was used as a drag reduction brine solution with surfactant. And the pipe friction coefficient and mean heat transfer coefficient of the EG solution flow with ODEAO were measured as parameters of EG concentration, solution temperature and ODEAO concentration. The experimental results indicated that the flow drag (heat transfer) reduction effect was lost when the wall shear stress exceeded a certain value. And the certain value of this wall shear stress (= maximum wall shear stress) increased with increasing the EG concentration, ODEAO concentration and brine temperature. On the other hand, the drag reduction mechanism of EG solution with ODEAO was investigated by comparing with the experimental results the ODEAO water solution

    The flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants have been investigated from the effective energy consumption in a pipeline system. In this study, Oleyldihydroxyetyl Amine Oxide (ODEAO) was used as a drag reduction surfactant additive, and Ethylene Glycol (EG) solution was selected as the brine. The pipe friction coefficient and mean heat transfer coefficient of the EG solution flow with ODEAO were measured as parameters of EG concentration, solution temperature and ODEAO concentration. The obtained experimental results indicated that the EG concentration exerted an influence on the flow drag and heat transfer reduction characteristics of the EG solution flow with ODEAO.

    The drag reduction of a water flow with new drag reducing surfactants (amine oxide type nonionic surfactants, mixtures of amine oxide type nonionic surfactants and betaine type amphoteric surfactants) which were selected as environmentally acceptable drag reducing additives was investigated experimentally. Addition of amine oxide type nonionic surfactants to hot or cold water can reduce flow drag in a turbulent pipe flow. The present research investigated how various ionic components dissolved in water affected this drag reducing effect. It was found that ionic impurities contained in the water affected the pipe flow drag reducing effect by amine oxide type nonionic surfactants. Moreover, it was clarified that the decrease in the pipe flow drag reducing effect was recovered by adding a mixture of amine oxide type nonionic surfactants and betaine type amphoteric surfactant to the water with ionic impurities.

    An experimental investigation was performed to determine continuous slurry ice making characteristics with water solution in a cooled horizontal pipe to provide fundamental information for a new ice thermal energy storage system. The experiments were carried out under various conditions such as water solution velocity, concentration of water solution, temperature of cooled pipe wall, and pump pressure. In this study, two kinds of cooled pipes were used; one is made of stainless steel tube for making slurry ice and the other is made of glass tube for visualization. The production behavior of the ice particles in the pipe is observed. It was found that the critical condition for continuous ice making was derived as a function of the experimental parameters. Consequently, The relationship between ice making rate and the parameters was clarified.

    This paper deals with the heat transfer enhancement of a water pipe flow with drag reduction surfactants. The surfactant water solution has a flow drag reduction effect, but, it is allowed to decrease the heat transfer to the water in a pipe. In order to enhance the heat transfer, some wire coil type turbulent promoters were inserted into the pipe. In the present study, the pipe friction and the heat transfer coefficient were measured under various experimental conditions of wire coil diameter, pitch and length.

The measured results of the physical properties of the test microcapsule water slurry, that is, thermal conductivity, specific heat, latent heat, and density, were discussed for the temperature region of solid and liquid phases of the dispersion material (paraffin). It was clarified that Eucken's equation could be applied to the estimation of the thermal conductivity of the microcapsule water slurry. Useful correlation equations of the thermal properties for the microcapsule water slurry were proposed in terms of temperature and concentration ratio of the microcapsule water slurry constituents.

    This research reports the freezing characteristics of sand molded with "the freeze mold method". The freeze mold method is the casting process where little water is added to cast sand then they are frozen and become harden as a mold. Instead of using organic hardener, this molding technology possibly reduces resources and environment loading.
    e aimed at the practical application of the freeze mold method and chose cold airflow as the medium taking heat away from the mold. At first the sand with water was filled into a rectangular container that is the test section. Then cold air flowed into the container. Consequently, the mold was cooled and frozen by the cold airflow.
    The freezing behavior of the sample by cold airflow was investigated experimentally under the conditions of added water amount, superficial velocity, inflow air temperature and fixed bed height As a result, the freezing completion time becomes long as the added water amount increases. However, an increase in the added water amount doesn't influence the pressure loss of the test section so much. Moreover, the empirical equation was derived to predict the freezing completion time.
    On the other hand, the heat and mass transfer characteristics in the cast sand were investigated, when the molten metal, which has the low-melting point, was fed into the frozen cast sand,.
    Additionally, numerical analysis of the freezing behavior about the water in the cast sand by cold airflow was carried out. The results of the numerical analysis give close agreement with the experimental results.

    This project of "Development of High-density Heat Storage and the Application Method of Latent Heat Emulsion Slurry for Energy Conservation" was supported by Grant-in-Aid for Scientific Research (B) (2) between 2001 and 2002. The purpose of this project was to obtain the data for academic systematization and practical application of latent heat storage material by analyzing basic information on the emulsion and the high-performance latent heat storage from a viewpoint of development of new energy system. In this project, Paraffin wax water emulsion at a low melting point was used as a solid-liquid phase change material.
    In this project, the most suitable latent heat emulsion slurry was selected for heat storage system at first. And the physical properties (particle size, thermal conductivity, specific heat, latent heat, viscosity, etc.) of selected emulsion were evaluated, and the useful correlative equations for these physical properties were derived. Direct-contact heat exchange method between a hot or cold air and Paraffin as PCM was selected for the latent heat-release from the emulsion. The temperature effectiveness, the sensible heat release/storage time and the latent heat release/storage time were measured as experimental parameters. The useful non-dimensional correlation equations for those parameters were derived in terms of non-dimensional emulsion layer depth expressed the emulsion layer dimension, Reynolds number for airflow, Stefan number and heat capacity ratio. Finally, this latent heat storage system was evaluated in comparison with the traditional latent heat storage system, and the usefulness of proposed latent heat emulsion system is elucidated.

    Recently, a thermal energy storage system for air conditioning has been developed actively for the purpose of saving energy and reducing the peak electrical demand in the daytime during summer. In particular, a great deal of attention has been paid to the ice thermal energy storage system since it would be beneficial to be able to utilize the large latent heat of melting ice.
    The objective of the present study is to investigate the ice slurry making characteristics by using cold air and water. The cold air, which is made for the compressed air blew into a vortex cooler, blow into an ice making section which filled with cold water. The pieces of ice forms in the water by direct contact heat transfer between cold air bubbles and water.
    It was observed the ice making characteristics under some parameters of air temperature, air flow rate, and height of water. It was found that ice could be made at -1℃ in air temperature, and that ice making efficiency is different by the case of cold air flow rate. In the case of high flow rate, that is over 100 Nl/min. ice making efficiency is over 90%. The results of the present study provide fundamental information for the new ice thermal energy storage system.

    Experimental investigations has been performed to determine thermophysical properties and dynamic adsorption/desorption characteristics of powder type organic absorbent composed bridged complex of sodium polyacrylate as a new kind of adsorption material. The effective thermal conductivity was measured with the transient hot wire method under various temperature and humidity of the powder absorbent. The dynamic adsorption/desorption characteristics of the powder adsorbent were also measured by using fluidized bed system. The powder adsorbent particles were packed into a rectangular vessel, and the air was flown from the bottom of the vessel. The experiments were carried out under various air temperature, relative humidity and flow velocity conditions. It was found that both adsorption and desorption processes of passing a moist air into the powder adsorbent particles layers were the isoenthalpy change. Finally, the obtained data of Sherwood number for mass transfer and nondimenional completion time for adsorption and desorption processes were correlated by means of Reynolds number, schmidt number, adsorbed water vapor mass ratio, and Stefan number.

    The present study investigated the thermophysical properties, the heat storage characteristics and the heat transportation characteristics of water solution of micro capsule, which contained paraffin wax as a latent heat storage material.
    The density, the specific heat, the heat of fusion, the thermal conductivity and the viscosity of the water solution of micro capsule were measured. As a result, it was found that the density and the specific heat and the heat of fusion of the water wolution of micro capcule were able to evaluate from the concentration and the properties of the component material. The thermal conductivity of the water solution micro capsule was also estimated by using the Eucken's model. The power law model was applied to express the viscosity of the water solution of micro capsule. And the pseudoplastic viscosity and the index number were expressed as a function of the temperature and the mass concentration of micro capsule.
    The heat storage characteristics of the water solution of micro capsule was investigated by using the direct contact heat transfer method. The water solution of micro capsule was filled in a rectangular vessel and fine air bubbles were induced from the bottom of the vessel. The effect of the air velocity, the air temperature and the layr height on the heat storage characteristics were investigated. In the case of the high air velocity condition, the air bubbles united each other and effective heat transfer area were decreased. Therefore, the heat storage process was delayd in the high air velocity condition. A non-dimensional correlation to predict the time taken for the complete heat storage was derived.
    The pressure drop characteristics of water solution of micro capsule in a straight circular tube were measured. The pressure drop in the tube was increased with an increase in the mass concentration of the micro capsule. Compared with the case of pure water, the heat transportation rate was obviously increased. This fact indicated that the initial cost for constructing pipe lines was expected to be lower than the case using pure water.

    A design and construction of the compact scale thermal storage system for home-use have been carried out to determine the optimum operation mode of the system. The experimental system consists mainly of production and storage unit, transporting loop, and consumption unit of the liquid ice. Production and storage unit of the liquid ice consists of refrigerator, evaporator, and storage tank. The evaporator was installed in the storage tank with its surface being coated with polyolefin tube. Liquid ice was produced by cooling aqueous binary solution in the tank. Liquid ice, which was produced in the tank, is derived to the thermal load unit by the circulating pump through the piping system with 20m long, and then returns to storage tank after its cold energy consumed. In the kexperiment, a variety of operation modes of the system, namely the combination of the time of production, storage, and consumption of the liquid ice, were set as the test parameters. Then the measurements of power-input of the refrigerator, thermal load, and ice-packing factor were carried out, and then the optimum operation mode was determined.
    2. RESULTS AND REMARKS
    (1) In the heat release operation mode, both the exit air temperature and released heat were kept almost constant until the ice particles in the liquid-ice finish to melt. Furthermore, after the ice particles in the liquid-ice has melt, cooling capacity remains enough to keep the operation by the sensible heat of aqueous solution.
    (2) Long-time opration in the production mode produces much more ice packing factor, while it reduces the temperature of the liquid-ice yielding the reduction of the performance of the refrigerator. Therefore, by taking all the factors, namely, power input to the refrigerator, cooling capacity, efficiency o heat-release mode, into the account, the optimum operation mode in the present study has been determined.

    An experimental study has been performed to investigate the direct contact heat transfer characteristics between air and liquid ice. The effects of concentration of solution, inlet-air temperature, height of liquid-ice bed, and the flow rate of inle-air on the heat-removal performances were extensively examined. The results revealed that the flow rate of inlet-air exertes considerable effects on the direct contact heat transfer characteristics, and that there might be an optimum condition of the flow rate of air for total removed heat. The average heat removal rate was favorably correlated by the flow rate of inlt-air and the temperature difference between inlet-air and equilibrium freezing temperature of initial concentration of solution.
    The experimental apparatus fundamentally consists of test section, cooling-brine circulating loop, and air cooling system. The fluidization air for the three-phase fluidized bed was utilized as the medium of direct contact heat transfer. Air was cooled and dehuminided in the air chamber in advance. After both the flow rate and the temperature of air and humidity were favorably controlled, it was introduced to the test section. The test section consists of a test bessel, a distributor, and the calming section. The test vessel is made of transparent lucite tube which has dimensions of 150 mm in inner diameter and 330 mm in length. In order to obtain the uniform air flow at the inlet of test section, stainless mesh (20 mesh) and the Nylon cloth (200 mesh) along with the distributor were utilized at the inlet of the tube.
    The testing liquid ice was made up by mixing the fine ice particles and ethylene-glycol solution whose temperature and concentration were set in prescribed value. Ice packing factor was set constant at 62%. The initial height of the testing liquid ice h_b was set at 170 mm throu the experiments.
    Experiments were carried out to study the direct contact heat transfer characteristics of the solid-air-liquid three-phase fluidized liquid ice-bed. The following conclusions may be drawn within the parameters covered in the present study.
    (1) The heat removal rate is affected by the flow rate of inlet-air mostly and the temperature of inlet-air and initial concentration of solution, while it is little affected by the height of the liquid ice bed.
    (2) The total removed heat decreases as the flow rate of air increases owing to mainly the heat generation by the friction between the wall and liquid ice.
    (3) The average heat removal rate is correlated by the following equation within the deviation of <plus-minus>15

    1.固・液二相静止層内単管周りの融解熱伝達
    初期水容液濃度が平均熱伝達挙動に及ぼす効果について検討した。その結果、一般に融解初期の平均熱伝達率は初期水容液濃度が低いほど大きいが,融解時間が経過すると,逆の挙動が観察される場合があることがわかった。これは,初期水容液濃度が低いほど,(1)熱拡散係数が小さい,(2)水溶液の粘性が小さい,などの理由に基づくものである。
    2.固・液二相静止層内管群よりの融解熱伝達
    単管の場合と異なり,ある融解時間において,平均熱伝達率が一時急激に増大することが判明した。これは可視化観察結果より,融解域の合体に基づく現象であることがわかった。すなわち,単一融解領域内に存在する成層(一般に下部成層の方が上部成層より温度ならびに濃度が高い)が合体することにより,融解域内の温度および濃度が一時的に低下し,かつ成層が消滅して対流が活発になるためである。
    3.固・気・液三相流動層内単管よりの融解熱伝達
    初期溶液濃度が平均熱伝達率に及ぼす効果について検討した。その結果,初期濃度が低いほど熱伝達率は大きくなることが判明した。これは,濃度が低い(層内温度が高い)方が熱容量が小さく,また粘性が小さいという物性値の差によるものである。ガラス粒子添加量には最適値が存在することが明らかになった。さらに,粒子 の効果につき検討する必要がある。
    4.固・気・液三相流動層内管群よりの融解熱伝達
    三段管群の場合の水平方向および垂直方向の熱伝達率分布につき検討した結果,いずれの熱流束および吹き込み空気量においても,管群内の熱伝達率は一様であることがわかった。管群の総熱交換量に対する送風動力割合に関し検討がなされた。約6倍から27倍高い熱伝達率を得た。

    An experimental study has been performed to investigate the production characteristics of liquid ice as a new phase change material (PCM) along three horizontal circular cylinders immersed in a cold air stream with spraying droplets of propylene-glycol aqueous solution. The experiments were carried out under a variety of experimental para-meters such as wind velocity, air temperature, and droplet mass flow rate. The test section is 800 mm long and 200 mm X 200 mm in cross section. Three lucite tubes of 25 mm in diameter, on which stainless foil of 50 mum in thickness was wound, were utilized as icing cylinders. The formation of the ice layer along the cylinders were extensively observed. The weight of the liquid ice produced in the wind tunnel were measured. For the present experiments, it was found that the most suitable condition for production of the liquid ice might be obtained.
    The experimental apparatus consists basically of a wind tunnel with refrigeration system and spray-generation system. The major components of the wind tunnel are test section, refrigeration system, fan, heaters, a box for collecting liquid ice, associated measuring instrumentations, and ductwork. The refrigeration system was composed of a compressor, driven by a 11.3KW AC motor, with two evaporator and brine-cooled condenser. Seven heaters, which are capable of 8.25 KW, were installed in the tunnel to provide an additional load on the refrigeration system. With these refrigeration system and heaters, the usable temperature range extended from +20 to -20゚C. A centrifugal axial fan of 0.75 KW in the wind tunnel was used, which was capable of maximum velocity of 10 m/s in the test section. The test aqueous binary solution was cooled in the reservoir in advance. Solution spray was generated and controlled by a series of nozzles located in the tunnel contraction upstream the test section.
    The effect of a variety of parameters such as wind velocity, air temperature, and droplet mass flow rate on the liquid ice production behavior along the cylinders were extensively determined. The following conclusions may be drawn within the range of parameters investigated.
    (1) Liquid ice layer formed on the top of the cylinders grows thicker with both decreasing air temperature and increasing wind velocity, and then blockages between the cylinders tend to grow up in short time.
    (2) The most suitable condition for production of the liquid ice might be in wind velocity U_a = 6 m/s and air temperature THETA_a = -12゚C in the present method.

    An experimental investigation has been performed to determine the efficient method to prevent the freeze-off which should be observed in a horizontal cooled circular tube. The experiments were carried out under a variety of conditions of airflow rate, water flow rate, cooled air temperature, inlet water temperature, and initial water level. Extensive photographical and visual observations of the developing ice layer along the tube wall were conducted along with the experimental determination of the characteristics of the freezing heat transfer. The effect of the flow separation induced by an orifice situated at the entrance section of an uniformly cooled circular tube was extensively determined.
    A. Free Convection Heat Transfer of Air-Water Layers
    (1) Initially cooled water in the tube flows downward along the tube wall. Next a secondary eddy is formed due to density inversion in the water, and it flows upward along the tube wall, while the initial downward flowing eddy becomes weaker.
    (2) The water at the air-water interface is supercooled by the density inversion, and this supercooled water gradually spreads to the tube bottom by free convection.
    (3) The local heat flux increases with the cooling rate, but the rate of increase is quite small during the experiment.
    B. Characteristics of Freezing Heat Transfer of Layered Air-Water Flow
    (1) The freeze-off region and steady-state region can be apparently classified by the equation, THETA_c = 1.92 x 10^<-1>Re_W0.35.
    (2) In the freeze-off region, there are three kinds of ice forms. Furthermore, in the steady-state region, there are two kinds of ice forms and no ice region.
    (3) Ice layer along the upper tube wall grows because of the splashing of the ripples at the air-water interface, which may be caused mainly by the developed ice layer and the ice transition (ice test formed).
    C. Effect of Flow Separation on the Freezing Heat Transfer and Freeze-Off
    (1) The flow separation increases the time from the start of experimental run to the onset of freeze-off condition. The time of freeze-off takes the maximum at d/D=1/2.
    (2) The ice-deposit formed in the separated region just downstream of an orifice is concave when d/D is less than 3/4.
    (3) The ice-deposit thickness along the length of the tube decreases and the station of the rapid expansion of flow passage tends to move upstream as the water-flow velocity increases.
    (4) The time of freeze-off decreases with a decrease in the tube diameter.
