• THERMO-DIFFUSION EFFECT ON UNSTEADY CONVECTIVE AND MASS TRANSFER FLOW OF A CHEMICALLY REACTING VISCOUS FLUID THROUGH A POROUS MEDIUM IN A VERTICAL CHANNEL WITH RADIATION AND DISSIPATION

Abstract

In this paper, we investigate the effect of chemical reaction on mixed convective heat and mass transfer flow of a viscous through a porous medium in a vertical channel with heat sources. The equations governing the flow , heat and mass transfer are solved by employing perturbation technique with aspect ratio d as perturbation parameter. The velocity, temperature and concentration distributions are investigated for different values of Sc, S₀, N₁, g, Ec. The rate of heat and mass transfer are numerically evaluated for different variations of the governing parameters.
