The effect of anisotropy on the steady fully developed mixed convection flow in a vertical porous channel is analytically studied. The side walls of the channel are prescribed by a constant heat flux and the flow at the entrance is upward, so that natural convection aids the forced flow. It is shown that the anisotropy parameter has a significant effect of the flow and heat transfer characteristics. We extend the study in 9 with the case of opposing flow by using Computer Algebra software.
