Abstract

An implicit finite difference method is used to analyze the natural convection boundary layer flow in a saturated porous medium resulting from combined heat and mass buoyancy effects adjacent to an inclined surface. Both the streamwise and normal components of the buoyancy force are retained in the momentum equations. The present formulation permits the angles of from the horizontal. Numerical results indicate that, as the buoyancy ratio or inclination parameter increase, the surface heat and mass transfer rates increase. These results are compared with the approximate similarity solutions that are obtained by neglecting the normal component of the buoyancy force in the momentum equations. It is shown that the approximate similarity solutions may significantly underpredict the heat and mass transfer rates for small values of inclination parameter.
