Numerical study on mixed convection heat transfer in a porous L-shaped cavity

A lid-driven L-shaped cavity filled with a porous medium is analyzed. The Galerkin weighted residual method is applied to obtain numerical solutions. The effect of the Reynolds number (Re = 1–100), Grashof number (Gr = 103–105) and Darcy number (Da = 10−5–10−3) on the velocity and temperature fields...
