EFFECTS OF HEAT SOURCE/SINK ON MHD FLOW AND HEAT TRANSFER OF A NON-NEWTONIAN POWER-LAW FLUID ON A STRETCHING SURFACE WITH THERMAL RADIATION AND SLIP-CONDITIONS

Non-Newtonian boundary layer flow and heat transfer characteristics over a stretching surface with thermal radiation and slip condition at the surface is analyzed. The flow is subject to a uniform transverse magnetic field. The suitable local similarity transformations are used to transform the non-linear partial differential equations into system of ordinary differential equations. The non-linear ordinary differential equations are linearized by using Quasi-linearization technique. The implicit finite difference scheme has been adopted to solve the obtained coupled ordinary differential equations. The important finding in this communication is the combined effects of Magnetic field parameterM, power law index n, slip parameter , radiation parameter R, surface temperature parameter , heat source/sink parameter S, local Eckert number Ec, temperature difference parameter r, generalized local Prandtl number Pr on velocity and temperature profiles and also the skin-friction coefficient –f''(0)and hea
