Heat transfer in a channel with porous walls of different permeability

The present investigation deals with the heat transfer by laminar flow of a viscous incompressible fluid in a channel with porous walls of different permeability. Like the solution of flow equations, the solutions of energy equations for the two cases of the absolute value of the first-wall normal velocity greater than or equal to the absolute value of the second-wall normal velocity and of the absolute value of the second-wall normal velocity greater than or equal to the first-wall normal velocity when both the walls are either subjected to suction or injection do not reduce the same by transferring the origin of coordinates from one wall to another.
