Free convection and mass transfer flow through a porous medium bounded by an infinite vertical limiting surface with constant suction

Steady two-dimensional free convection and mass transfer flow, of an incompressible viscous fluid through a porous medium bounded by a vertical infinite limiting surface (plane wall) is considered. Expressions for the velocity, temperature, concentration and the rate of heat transfer are obtained. Effects of Gr (Grashof number), Gm (modified Grashof number) and permeability K of the porous medium on the velocity and rate of heat transfer are discussed when the surface is subjected to a constant suction velocity.
