HEAT AND MASS TRANSFER ANALYSIS ON MHD MIXED CONVECTION FLOW OF RADIATIVE CHEMICALLY HEAT GENERATING FLUID WITH VISCOUS DISSIPATION AND THERMO-DIFFUSION EFFECT

In this paper an analysis on heat and mass transfer is made to study magnetohydrodynamic (MHD) mixed convective flow of an incompressible viscous fluid flowing past an inclined plate. A magnetic field of uniform strength is applied to the plate to influence the flow. Due to weak voltage differences caused by the very low polarization charges, the influence of electric field is considered to be neglected. Again large temperature gradient ensures cross diffusion effect like thermo-diffusion (Soret) in the field. The governed set of non-linear partial differential equations is solved by developing a multi-parameter asymptotic perturbation scheme. The influence of various physical parameters such as heat source parameters (Qs), chemical reaction parameter (CR), magnetic field parameter (M), Eckert number (Ec), thermal radiation parameter (R), permeability parameter (K) and plate inclination parameter (ψ) on the velocity, concentration and temperature profiles as well as skin-fraction, Nusselt number and Sherwood number are simulated numerically for the study. It reveals that, an increase in magnetic field parameter (M) decreases the axial velocity field, coefficient of skin-friction and Sherwood number but increases Nusselt number, temperature and concentration profiles. Again an increase in Eckert number (Ec) decreases both the co-efficient of skin-friction and Nusselt number while increases the temperature, Sherwood number and concentrations of the fluid particles.
