The Effects of Thermal Radiation, Heat Generation, Viscous Dissipation And Chemical Reaction on MHD Micropolar Fluid Past Stretching Surface in a Non-darcian Porous Medium

B. Lavanya & A. Leela Ratnam

The main concern of present study is to investigate the effects of thermal radiation and chemical reaction on a steady two-dimensional laminar flow of a viscous incompressible electrically conducting micropolar fluid past a vertical isothermal stretching surface embedded in a non-Darcian porous medium in the presence of viscous dissipation and heat generation. The governing equations of momentum, angular momentum, energy, and species equations are solved numerically using Runge-Kutta fourth order method with the shooting technique. The effects of various parameters on the velocity, microrotation, temperature and concentration field as well as skin friction coefficient, Nusselt number and Sherwood number are shown graphically and tabulated. It is observed that the micropolar fluid helps in the reduction of drag forces and also acts as a cooling agent. An excellent agreement is observed between some of the obtained results of the current study and those of previously published studies.
