Abstract

Unsteady boundary layer flow and heat transfer characteristics of a viscous fluid through porous media have been studied in the case of variable viscosity and variable Prandtl number. The plate surface is embedded in a uniform Darcian porous medium. In order to allow for possible fluid wall suction or blowing the plate is assumed to be uniformly porous. The similarity transformation is used to transform the system of partial differential equations, describing the problem under consideration, into a system of coupled ordinary differential equations. Analytic and numerical solutions of these equations are obtained using the homotopy analysis method and Runge−Kutta shooting technique, respectively. The results are presented graphically and it is concluded that the flow field and other quantities of physical interest are significantly influenced by the involved parameters.
