Abstract

Results of the numerical solution of the mass conservation, DBF, and energy equations are presented. Verification of the solution method is first obtained by reproducing solutions for Rayleigh-Bénard convection, the Horton-Lapwood-Rogers program, and natural convection in fluid-superposed porous layers. For mixed convection in the fluid-superposed porous layer, Nusselt numbers are determined for a wide range of parameter effects: conductivity ratio, thermal dispersion, Prandtl number, Darcy number, and porous layer height ratio. Péclet numbers at which a minimum in the heat transfer coefficient occurs are determined in terms of combinations of these parameters.
