Abstract

This paper presents the effects of suction and blowing on an axisymmetric flow and heat transfer of an electrically conducting fluid over a non-linearly stretching porous sheet. A uniform magnetic field is applied normal to the stretching sheet. The stretching velocity is assumed to be proportional to the power law of radial distance.  The governing boundary layer equations are reduced into highly nonlinear ordinary differential equations by a similarity transformation. The reduced equations are then solved numerically by finite element method for power-law temperature boundary conditions. It is found that radial velocity is decreased for enhanced values of magnetic field and suction at the sheet and is increased with the increasing values of blowing parameter. It is also observed that the thermal boundary layer thickness increases with the increase in magnetic and blowing parameter whereas it decreases with the increase in suction parameter, power-law parameter of stretching velocity, Prandtl number and power law index of the surface temperature distribution.
