MHD stagnation flow towards a porous stretching sheet with suction or injection and prescribed surface heat flux

The objective of the present study is to analyze the effect of heat generation/absorption on magnetohydrodynamic stagnation point flow and heat transfer over a porous stretching surface, with prescribed surface heat flux. The governing coupled partial differential equations are non-dimensionalized and solved analytically by homotopy perturbation method employing Padé technique. The effects of involved parameters (stretching velocity, magnetic parameter, porosity parameter, suction or injection parameter, heat flux index, heat source or sink parameter, Prandtl number) on velocity, temperature profiles are presented graphically and analyzed. The obtained results are compared with the numerical solution and with other results obtained in previous works so that the high accuracy of present results is clear.
