INFLUENCE OF SORET EFFECT, HEAT SOURCE, VISCOUS DISSIPATION, CHEMICAL REACTION, THERMAL RADIATION AND VARIABLE PERMEABILITY ON HEAT AND MASS TRANSFER THREE DIMENSIONAL FREE CONVECTIVE MHD FLOW THROUGH POROUS MEDIUM

In the present study, the influence of Soret effects, Heat Source, Thermal Radiation, Viscous Dissipation and Chemical Reaction on three-dimensional free convective MHD flow through porous medium with variable permeability was examined.The dimensionless governing equations were solved analytically by Multiple Regular Perturbation Law.The effects of several flow parameters affecting velocity, temperature and concentration were explained and discussed graphically.The expressions for the skin friction, Nusselt number and Modified Nusselt Number profiles were formulated and discussed with the help of tables.It is observed that the velocity of the fluid initially increases and then decreases with increase of y but it showed reverse behaviour with large increase in radiation parameter (R).
