Magnetohydrodynamic Radiative Casson Fluid Flow over a Stretching Sheet with Heat Source/Sink

Abstract

The influence of heat source/sink and thermal radiation on steady magnetohydrodynamic flow of a Casson fluid past a permeable stretching sheet was analysed numerically. We considered nanofluid volume fraction on the boundary is submissive controlled. The transformed equations governing the flow are solved numerically using bvp5c Matlab package. Effects of non dimensional governing parameters on velocity, temperature and concentration profiles are discussed and presented through graphs. Results indicate that the enhancement in Brownian motion and thermophoresis parameters depreciates the nano particle concentration and increases the mass transfer rate.
