Darcy‐Forchheimer mixed convection heat and mass transfer in fluid saturated porous media

Abstract

The Darcy‐Forchheimer mixed convection from a vertical flat plate embedded in a fluid‐saturated porous medium under the coupled effects of thermal and mass diffusion is analyzed on the basis of boundary‐layer approximations. Similarity solutions are obtained for the case of constant surface temperature and concentration. Numerical results are presented for the distribution of velocity, temperature and concentration profiles within the boundary layer. Representative heat and mass transfer rates in terms of Nusselt and Sherwood numbers for various governing parameters are presented and discussed.
