We made an attempt to study thermo-diffusion and chemical reaction effects on non-Darcy convective heat and Mass transfer flow of a viscous electrically conducting fluid in a vertical channel with heat generating sources. The Brinkman Forchhimer extended Darcy equations which takes into account the boundary and inertia effects are used in the governing linear momentum equation. The effect of density variation is combined to the buoyancy term under Boussineq approximation. The momentum, energy and diffusion equations are coupled equations. In order to obtain a better insight into this complex problem, we make use of Galerkin finite element analysis with Quadratic Polynomial approximations. The Galerkin finite element analysis has two important features. The first is that the approximation solution is written directly as a linear combination of approximation functions with unknown nodal values as coefficients. Secondly, the approximation polynomials are chosen exclusively from the lower order Piecewise polynomials restricted to contiguous elements. The velocity, temperature, concentration, shear stress and rate of Heat and Mass transfer are evaluated numerically for different variations of parameter.
