摘要
顶部放热的矩形空间多孔介质中自然对流陈振乾施明恒（东南大学动力工程系，南京２１００１８）多孔介质中流体的流动和传热在地热利用、太阳能利用、石油热采、核能开发及某些化工过程中有重要的应用［１］，特别对太阳能储热和地热资源的开发更具有重要的意义．通常，...
A mathematical model of natural convection inside porous media in a closed rectangular cavity with local cooling on top is estabidhed. Flow field, temperature field and their variation with the main parameters are obtained by numerical method. The results show that Rayleigh number and local cooling aspect ratio have great effects on flow characteristics, temperature distribution and natural convection heat transfer intensity.
