Thermal Radiation Effects on Mhd Free Convection Flow of a Micropolar Fluid Past a Stretching Surface Embedded in a Non-Darcian Porous Medium

A comprehensive study of thermal radiation on a steady two-dimensional laminar flow of a viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-Darcian porous medium is analyzed numerically. The governing equations of momentum, angular momentum, and energy equations are solved numerically using Runge- Kutta fourth order method with shooting technique. The effects of various parameters on the velocity, microrotation, and temperature field as well as skin friction coefficient, and Nusselt number are shown graphically and in tabulated. It is observed that the micropolar fluid helps in the reduction of drag forces and also acts as a cooling agent. KEYWORDS: Micropolar fluid, Free convection, Darcy number,Radiation, MHD, Porous medium
