The present paper aims to study thermo-diffusion, diffusion-thermo effects and chemical reaction effects on non-Darcy convective heat and mass transfer flow of a viscous fluid through a porous medium in a vertical channel with heat generating sources. The governing equations of flow are solved by using Galerkin finite element method (GFEM) with quadratic polynomial approximations. The velocity, temperature, concentration, shear stress and the rate of heat and mass transfer are evaluated numerically for different variations of parameter. The results obtained are compared with available literature and found to be in good agreement.
