Abstract:A 2D heat and mass transfer mathematic model in enclosure rectangle packed with porous media is established. To be further, the numerical simulation is carried out. According to concerned analysis based on the calculated result, the effects on the heat and mass transfer characteristics caused by the change of the Raleigh number, the Darcy number, the temperature deference between the hot and the cold wall of the enclosure is emphatically discussed.
Keywords:enclosure rectangle  unsaturated porous media  heat and mass transfer  numerical sim- ulatio
