摘要：

In this study, volume-averaged equations governing the steady mixed convection flow in a vertical square enclosure filled with a non-Darcian fluid-saturated homogeneous porous medium are investigated numerically by the Galerkin finite element method. The forced flow conditions are imposed by providing an inlet at the bottom wall and an outlet with suction on the top wall. The free convection is induced by introducing a hot but isothermal temperature on the left vertical wall together with Boussinesq approximation on density. Detailed numerical simulations are carried out for a wide range of governing parameters such as Grashof Number (Gr*), Rayleigh Number (Ra), suction/injection velocity (a), and suction/injection width (D/H) as a fraction of the length of the square enclosure.
