MHD stagnation point flow and heat transfer over a permeable surface through a porous space

This article investigates the heat transfer analysis for magnetohydrodynamic flow of a viscous fluid at a stagnation point. The viscous fluid filling the porous space is bounded by a permeable surface. Employing similarity transformations, the governing partial differential equations are transformed into ordinary differential equations. The resulting nonlinear system has been solved analytically using a very efficient technique, namely, the homotopy analysis method. Series solutions for velocity and temperature fields are developed. The effects of various emerging parameters are seen on the velocity and temperature fields. The values of the wall shear stress are also tabulated for different cases.
