Free-convection magnetohydrodynamic flow for non-Newtonian fluid past porous flat plate

In this paper the steady motion of an electrically conducting, viscous and incompressible non-Newtonian fluid past a porous flat plate under a transverse magnetic filed is considered. Analytically expressions for the velocity, temperature, skin friction and magnetic induction have been obtained by using the perturbation technique. Our results are compared with the previous ordinary Newtonian fluid results. The results have been shown graphically, and the effect of different parameters on the velocity, the magnetic induction, coefficient of skin friction and temperature are discussed in these cases.
