MHD flow of second grade fluid over an infinite permeable plate embedded in a porous medium

摘要

In this paper, we have studied the heat transfer in a laminar MHD flow of heat generating /absorbing second grade fluid on permeable surface. The dimensionless governing equations are solved to the best possible analytical solution. The influence of various participating parameters are illustrated graphically and explained in detail. It is noticed that, far away from the bounding surface it is seen that a wide spreading in the velocity profiles is observed. Such a phenomena could not be observed in boundary layer region as the porosity of the bounding surface decreases, not much of change in the velocity field is noticed. Also, as the pore size of the fluid bed decreases the velocity is seen to be increasing. The Shear stress and Nusselt number are calculated and discussed with reference to governing parameters.
