Thermal radiation effect on MHD nanofluid flow over a stretching sheet

Abstract

The present study is a numerical investigation of heat and mass transfer in twodimensional MHD stagnation point flow of a radiative Carreau nano fluid past a stretching surface in the presence of Soret and suction/blowing effects. The governing partial differential equations are transformed into a set of ordinary differential equations by using approximate self similarity transformation and solved numerically using Runge-Kutta and Newton's methods. The graphical and tabular results elucidate the influence of different non-dimensional governing parameters on the velocity, temperature and concentration fields along with the wall friction, local Nusselt and Sherwood numbers. We found the dual nature of the solutions for Newtonian and non-Newtonian fluid cases. © 2016 Trans Tech Publications, Switzerland.
