EFFECT OF NON-LINEAR DENSITY VARIATRION ON CONVECTIVE HEAT AND MASS TRANSFER FLOW IN A CYLINDRICAL ANNULUS WITH SORET,CHEMICAL EFFECTS AND RADIATION ABSORPTION

Abstract

In this Paper, We analyze the effect of thermo-diffusion and diffusion- thermo on non-Darcy convective heat and mass transfer flow of a chemically reacting, radiating fluid through a porous medium in a Co-axial cylindrical duct in the presence of dependent heat source with non-linear density temperature variation. The boundaries are maintained at temperature Tw and Concentration Cw. The behavior of velocity, temperature and concentration is analyzed at different axial positions with pertinent parameters. The shear stress and the rate of heat and mass transfer have also been obtained for variations in the governing parameters by employing finite element technique. Effect of pertinent parameters on velocity, temperature and concentration fields is examined through the plots. Skin-friction coefficients, Nusselt number and Sherwood number for different variations are studied numerically.
