Effects of Radiation and Heat Dissipation on Free Convective Heat and Mass Transfer Flow through a Porous Medium

Mathematics

This paper investigates the effects of radiation and heat dissipation on free convective heat and mass transfer flow through a porous medium. Solutions of time dependent energy, momentum and concentration equations under the relevant initial and boundary conditions were derived using perturbation technique. Selected set of line graph representing the effect of controlling parameters embedded in the problem are discussed during the course of numerical computation. It is observed that, an increase in Gr and Gm results in the thickening of the thermal boundary layer, which leads to an increase in the velocity layer. However, increase of variable parameter Prandtl number, results in the increase in temperature and decrease with radiation.
