Abstract

We analyze the combined influence of Brownian motion, thermophopresis, with past a stretching surface with variable viscosity and thermal radiation. The governing equations have been solved by employing fifth-order Runge-Kutta-Fehlberg method along with shooting technique. The effects of various parameters on the velocity, temperature and concentration as well as on the local skin-friction coefficient, local Nusselt number and local Sherwood number are presented graphically and discussed. It is observed that a velocities component increases with Hall parameter(m), Brownian motion parameter (Nb), Radiation parameter (Rd), Viscosity parameter (r), Convective heat transfer constant(h1), reduces with thermophoresis parameter (Nt). Nusselt number increase in r and reduces Nu and Sh, increase in r/h1 reduces rate of heat transfer and enhances mass transfer.
