Unsteady Hydromagnetic Flow and Radiation Heat Transfer Past a Stretching Surface Embedded in a Porous Medium with Dissipation Effects

Abstract

Abstract This paper presents a mathematical analysis on the effects of viscous dissipation over unsteady MHD flow and radiation heat transfer past a stretching surface subjected to suction embedded in a porous medium. The governing nonlinear partial differential equations of the problem are transformed into nonlinear ordinary differential equations adopting suitable similarity transformations. The numerical solution is obtained by employing Nachtsheim-Swigert shooting iteration method together with Fourth order Runge-kutta integration method. Numerical results for the dimensionless velocity and temperature distribution as well as for the local skin friction coefficient and nondimensional rate of heat transfer are obtained and displayed graphically for pertinent physical parameters.
