Nonlinear Thermal Radiation and Chemical Reaction Effects on MHD 3D Casson Fluid Flow in Porous Medium

Abstract

In this study, we analyzed the influence of nonlinear thermal radiation and viscous dissipation on three-dimensional MHD Casson fluid flow over a stretching surface in the presence of chemical reaction. The transformed governing equations are solved numerically using Runge-Kutta based shooting technique. The influence of non-dimensional parameters on velocity, temperature and concentration profiles along with the friction factor, local Nusselt and Sherwood numbers are discussed with the help of graphs and tables. It is found that an increase in the nonlinear thermal radiation parameter enhances the temperature profiles of the flow.  Chemical reaction parameter have tendency to enhance the mass transfer rate.
