Abstract

The flow and heat transfer problem of a viscous electrically conducting viscoelastic fluid over a semi-infinite unmagnetized but conducting plate with an aligned magnetic I field and a magnetodynamic pressure gradient proportional to some power of distance along the boundary has been studied. The governing equations have been solved numerically using Keller Box method. The effects of the viscoelastic parameter, the magnetic parameter, the magnetic Prandtl number, the pressure gradient parameter, the Eckert number and the fluid Prandtl number on the surface shear stress, the x-component of the induced magnetic field and the heat transfer parameter have been studied in detail. The surface shear stress, the induced magnetic field in the x-direction at the wall and the heat transfer at the wall decrease as the magnetic parameter or the viscoelastic parameter increases. The x-component of the induced magnetic field at the wall is strongly dependent on the magnetic Prandtl number. On the other hand, the heat transfer parameter is strongly dependent on the Prandti number and the Eckert number.
