MHD Non-Newtonian Power Law Fluid Flow and Heat Transfer Past a Non-Linear Stretching Surface with Thermal Radiation and Viscous Dissipation

Abstract

Non-Newtonian magneto-hydro dynamic boundary layer flow of an electrically conducting power law fluid flowing over a non-linear stretching surface in the presence of thermal radiation, taking into account the viscous dissipation effects is investigated. By using quasi-linearization technique first linearize the non linear momentum equation and then the coupled ordinary differential equations are solved numerically by an implicit finite difference scheme. The numerical solution is found to be dependent on several governing parameters. A systematic study is carried out to illustrate the effects of various parameters on the fluid velocity and the temperature distribution in the boundary layer through graphs. The results for the local skin-friction coefficient and the local Nusselt number are tabulated and discussed and found to be in good agreement with earlier published results.
