# 用格子Boltzmann方法分析太阳墙系统温度和速度的传输特性Analysis of the ransfer Characteristics of the Temperature and Velocity in the Solar-Wall System by Lattice Boltzmann Method

In this paper, the characteristics of heat transfer and air flow in the solar wall and heated room are analyzed by Lattice Boltzmann Method simulation. We studied the air flow in the porous wall and the heat transfer of the heated room under different parameters, such as velocity of the fan, porosity of the porous medium and diameter of the upper channel etc. The results show that changing parameters have a remarkable effect on temperature of the air flowing through the porous medium and the heated room. As a result, choosing the parameters properly can effectively improve the heat utilization efficiency of the porous wall and the thermal comfort of the room.
