MHD stagnation point flow over a stretching or shrinking sheet in a porous medium with velocity slip

Abstract

Magnetohydrodynamics (MHD) stagnation point flow in a porous medium with velocity slip is investigated in this study. The governing system of partial differential equations is transformed into a set of non-linear ordinary differential equations by using the similarity transformation. Subsequently, the transformed equations are numerically solved by using the shooting method in MAPLE software. The skin friction coefficient and the local Nusselt number are obtained and presented graphically. The effects of the governing parameters including the velocity slip, magnetic and permeability parameters, are examined. It is found that both the skin friction coefficient and the local Nusselt number increase as magnetic and permeability parameters increase.
