• EFFECT OF POROUS MEDIUM ON UNSTEADY LAMINAR FREE CONVECTIVE FLOW OF DUSTY VISCOUS FLUID WITH THERMAL DIFFUSION, HEAT AND MASS TRANSFER

Abstract

The purpose of the present problem is to study the effect of porous medium on unsteady laminar free convective flow of dusty viscous fluid along a moving porous hot vertical plate in the presence of heat source and thermal diffusion with heat, mass transfer and hall currents. The governing equations of motions are solved by a regular perturbation technique. The velocity of dusty fluid and dust particles and skin friction are discussed with the help of tables and graphs. The velocity of dusty fluid and dust particles increase with the increase in K1 (Porosity parameter) and Q (Velocity ratio parameter), but it decreases with the increase in M (Hartman number).
