The finite volume method (FVM) is used to dis-cretize the governing momentum and energy equations. The behavior of velocity and temperature contours, and similarly velocity and temperature profiles against pertinent parameters like the Hartman number Ha and dimensionless permeability factor K are displayed graphically for different channel configurations and explained in a physical manner. Physical quantities of interest such as bulk mean velocity ωm and friction factor fRe are used to explain the fluid flow behavior, whereas the bulk mean temperature τb and average Nusselt number Nu are used to explain the heat transfer analysis. Their values are also computed numerically and compared with the literature in the limiting case.
