MHD Thermal Stagnation Point Flow towards a Stretching Porous Surface

Abstract

This paper presents an investigation of the hydromagnetic stagnation flow of an incompressible viscous, electrically conducting fluid, towards a stretching sheet in the presence of axially in- creasing free stream velocity. The Newton-Raphson shooting method along with the fourth-order Runge-Kutta integration algorithm has been employed to tackle the third order, nonlinear boundary layer equation governing the problem. The results indicate that suction and thermal Grashof number have the same effect on the rate of heat transfer. The magnetic parameter has the effect of increasing the skin friction coefficient whilst the reverse is observed for increasing the velocity ratio parameter.
