BUOYANCY OPPOSED MIXED CONVECTION IN A TWO-SIDED LID-DRIVEN DIFFERENTIALLY HEATED SQUARE CAVITY FILLED WITH A POROUS MEDIUM
ABSTRACT
Mixed convection flow in a two-dimensional square cavity filled with a Darcian fluid-saturated uniform porous medium is considered. The cold vertical wall at the left is moving up whereas the hot wall in the right is moving down. The fixed top and the bottom walls are thermally insulated. The normalized governing equations are solved numerically with appropriate boundary conditions by finite volume approach. The code has been validated with previously published work and the results are found to be in excellent agreement. The study is conducted by varying the Richardson number Ri = (Gr/Re2)[Ri = (Gr/Re2)], Darcy number (Da = κ/H2κ, Grashof number Gr = (gβΔTH3/v2)[Gr = (gβΔTH3/v2)]. The Prandtl number is fixed at 0.71. A parametric study is conducted and a set of streamlines and isotherm plots are presented. A heat transfer correlation is also presented.
