The present analysis is concerned with the flow and heat transfer characteristics of the fully developed laminar mixed convection in a vertical channel embedded in porous media with asymmetric wall heat fluxes. The exact solutions of the velocity profiles and temperature distribution as well as the Nusselt number in terms of bulk mean temperature are derived by using non-Darcy flow model. The investigation of Darcy resistance is shown to demonstrate the effect due to the porous material. Finally, Parameter zones for the occurrence of reversed flow are also presented.
