Finite Element Analysis of the Heat Transfer Problems of PCMs

摘要：

　　Finite element method (FEM) was used for analyzing the heat transfer problems of the PCMs and phase change gypsum board.The simulation results showed that the heat transfer rate of composite PCMs(phase change materials) is higher than the PCMs,the mixture of diatomite improved the heat transfer performance of PCMs.Compared with blank gypsum board,the cold side temperature of phase change gypsum board was decreased,and the temperature rise rate of the cold side was also delayed.The cold side temperature difference between gypsum board and phase change gypsum board was decreasing as the ongoing of heat transfer process.
