Effects of viscous and joulean dissipations on hydro-magnetic free convection flow over a heated surface

Abstract

In this paper, effects of viscous and Joulean dissipations on hydro-magnetic convection flow on an incompressible fluid with temperature dependent viscosity over a stretching surface have been studied numerically using MATLAB 6.1. The results for velocity and temperature distribution, local skin friction coefficient, and surface heat flux coefficients have been investigated and discussed for different values of the parameters encountered in the equations.
