摘要：
A fluid convection flow driven by a uniformly movable lid with thermosolutal stratification in a square enclosure filled with a porous medium is studied. A wide range of Grashof numbers, 10(4) <= Gr <= 10(6), and Reynolds numbers, 500 <= Re <= 2500, have been investigated for the flow, heat, and mass transfer characteristics. The porosity inside the enclosure is chosen to be 0.4 for the Darcy number varying from 10(-4) to 1.0. A detailed comparison of the flow, heat, and mass transfer is made in this article. The average rates of heat and mass transfer from the top and bottom lids on the flow parameters are also investigated.
