Abstract

In the present paper the behavior of the free convective boundary layer flow of an electrically con-ducting visco-elastic,incompressible fluid through a porous medium over a continuously moving surface in the presence of uniform magnetic field with constant suction is studied. A uniform magnetic field is assumed to be applied perpendicularly to the moving surface. A similarity transformation is used which reduces the partial differential equation to ordinary differential equation. The velocity and temperature field is obtained. The effect of Reynolds number (Re), Hartmann number (H), Grashof number (Gr), viscoelastic parameter (K0) and permeability parameter (K) on velocity field and temperature field are discussed with the help of graphs.
