铝泡沫和石墨泡沫强化石蜡相变传热的数值模拟
Numerical Simulation of Heat Transfer Enhancement of Paraffin Wax Phase Change with Mmetal Foam and Graphite Foam
摘要
Abstract
Aiming at the problem of low conductivity of organic phase change material, two-dimensional numerical simulation on heat transfer enhancement of phase change of paraffin wax by adding porous media was conducted with the CFD software. The results showed that both Al foam and graphite foam could improve heat transfer rate effectively, and the effect of heat transfer of Al foam is superior to that of graphite foam, and the effective thermal conductivity of porosity/ paraffin wax composite materials is greater, heat transfer rate is faster; the solidification time shorten. And the temperature of corresponding points in device is lower after the same solidfication time with the decrease of porosity.关键词
