Abstract
Similarity solution for the problem of hydrodynamic dispersion and radiation in non- Darcy mixed convection heat and mass transfer from vertical surface embedded in porous media is presented. The Forchheimer extension is considered in the governing equations. The heat and mass transfer in the boundary layer region for aiding and opposing buoyancies in both flows has been analyzed. The Rosseland approximation is used to describe the radiative heat flux in the energy equation. The dimensionless velocity, temperature and concentration fields in the non-Darcy porous media are governed by complex interactions among the diffusion rate, buoyancy ratio and radiation parameter in addition to the flow driving parameter. Numerical results for details of the dimensionless velocity, temperature and concentration which shown on graphs and tables have been presented and compared against previously published work on special cases of the problem and found to be in excellent agreement. The combined effects of radiation, thermal dispersion and solutal diffusivity, for the non-Darcy porous medium, on the dimensionless velocity and heat and mass coefficients are discussed.
