摘要
从合湿多孔封闭腔内流体流动与传热特征出发，提出了一种线性近似假设法，并用该法对矩形封闭腔内含湿多孔介质的自然对流行为进行了近似分析求解，得到了其温度分布、速度分布与传热数表达式．
Utilizing the characteristics of natural convection in a rectangular enclosure packed with porous media, with linear approximate assumption, an analytical solution of it is obtained. The analytical solution results are in good agreement with that from numerical calculations When the aspect ratio A>3 and the modified Raleigh number Ra# = 10￣250.
