Abstract:The steady-state flow field and temperature distribution inside a thermal cycling test chamber with nonuniform perforated plate are investigated both numerically and experimentally. Porous zones are set up by pressure loss analogy to simplify the perforated plate. Boussinesq approximation and low-Re model are used in the simulation. The numerical result shows both forced convection and natural convection contribute to the fluid flow and heat transfer. For uniform perforated plate, the temperature at the given height always increases from the center line to the walls. And from top to bottom of the cycling chamber, temperature increases around the center line while decreases near the walls. Based on that, two cases of nonuniform perforated plates with the same ratio of open area and different holes distribution are examined to improve the temperature uniformity in test chamber. The results show that both average temperature and standard temperature deviation are effected significantly by nonuniform perforated plate. The latter experiment is performed with the optimal perforated plate under the same condition of Re=4.1×10^4, Gr=1.8×10^11. The experiment results are obtained by Constant Temperature Anemometry and agree with the numerical simulation. | |||

Abstract:Ice slurry, as a very attractive coolant which can outperform many single-phase heat transfer fluid medium in energy storage denstiy due to latent heat from fusion of ice crystals has attracted great attention. However, the size increase and shape change of ice crystal when stored adiabatically, not only decreases the melting rates of ice slurries in heat exchange but also can result in pressure drop or even fatal clogging in pipes. This seriously hinders the widely practical use of ice slurries for transport of cold energy. Efforts must be put to inhibite the ice crystal growth. This paper reviews ice crystal growth characterization and its growth control by using additives. Additives include anti-freeze protein (AFP) and the substitute such as polyvinyl alcohol (PVA), silane coupling agents and surfactants. For AFP and PVOH, the mechanism of growth control is thermal hysteresis, while, for surfactants, the mechanism has not been reported. Function groups of additives that cause adsorption are summarized. And the issues that crying needs to be solved to expand the ice slurry utilization is given. The review will help people fully understand the research status of ice crystal growth. | |||

Abstract:Graphene defects have played an important role in graphene's electrical, optical and thermal properties. In this work, we measured the interface thermal conductance of Al/graphene with different defect situations/silica using transient thermoreflectance technique. We use the graphene thermal stability of being annealed in different temperatures to manipulate the graphene defects. The transient thermoreflectance technique measurement results suggest that as graphene defects increase, the interface thermal conductance increases as well. The cause of the interface thermal conductance increase might be the graphene disintegration which starts from graphene imperfection rings and the oxygen doping which will enhance the metal-graphene bonding energy. | |||

Abstract:Coupled conduction and radiation heat transfer problems were solved using the based-cell and the finite volume method (FVM) in the regions with the mediums. The combined heat transfer equations were discretized in the unstructured meshes and the calculating programs were written. The radiative heat source of the combined equation was treated specially. Meanwhile, from the relations of the governing equations and the several of medium characters, the dimensionless numbers were obtained and computed using unstructured quad grids in various parameters, such as, optical thickness τ, conduction-radiation parameter N, and scattering albedo ω. | |||

Abstract:Conduction heat transfer problems were solved using a cell-based finite volume method. Solutions were obtained using structured and unstructured grids. When available, results were compared with exact solutions. Although both structured and unstructured grids produce accurate solutions, structured grid solutions are more accurate. The secondary diffusion term is important if accurate solutions were to be obtained. | |||
