ABSTRACT

The effect of porosity on the steady flow of an incompressible viscous fluid impinging on a permeable surface is investigated with heat transfer. A numerical solution for the governing nonlinear momentum and energy equations is obtained. The effect of the porosity of the medium and the suction or injection velocity on both the flow and heat transfer are outlined. The results indicate that increasing the porosity parameter M decreases both the velocity and thermal boundary layer thickness. On the other hand, the wall shear stress increases with increasing porosity of the medium.
