摘要
根据多孔介质的孔隙及颗粒的大小和多孔腔内水分的静态分布特性，将封闭腔内含湿多孔介质的流动与传热划分为低Ｄａ数与高Ｄａ数两类流动问题。同时采用二维无量纲非稳态模型对低Ｄａ数封闭多孔腔内的热湿迁移特性进行了数值模拟。
The flow and heat transfer in an enclosure filled with unsaturated porous media has beendivided into two categories,the flow atmgh Darey number and that at low Darcy number ac-cording to the static distribution characteristic of free water in pores and the sizes of poresand particles.Atransient non-dimensional model is developed to simulate heat and moisturetransport in a porous enclosure with low Darcy number and the transport properties of heatandmoisture in the enclosure are also analyzed.
