• NONLINEAR RADIATION EFFECT ON CASSON FLUID SATURATED NON-DARCY POROUS MEDIUM

Abstract

This paper deals with the study of MHD non-Darcy Casson fluid flow induced due to a vertical porous stretching surface in the presence of nonlinear thermal radiation, viscous dissipation and first order chemical reaction. Similarity variables have been employed to transform the governing non-linear boundary layer equations into a set of non-linear ordinary differential equations. Numerical solutions are obtained for the velocity, temperature and concentration using shooting technique and Runge - Kutta method. Comparison of our results under limiting cases is made with the already published results. To understand the influence of the physical parameters, flow characteristics are evaluated and graphically presented for different variations of governing parameters. The Nusselt number and Sherwood number are also evaluated and discussed.
