摘要:
本文主要应用格子Boltzmann方法研究太阳墙以及采暖房的热量传递和空气流动特性。通过改变参数，例如：风机的速度，多孔介质的孔隙度和上通道的直径等，进行数值模拟，研究在不同的参数下通过多孔介质的空气温度和流速，以及采暖房的温度分布等问题。数值模拟结果表明：参数的不同对流经多孔墙的空气的温度，以及采暖房的温度分布有着显著的影响，适当的选择参数可以有效的提高多孔墙的热利用率和房间的热舒适性。
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.
