Study of Unsteady MHD Free Convection Flow past a Vertical Plate with Thermal Diffusion and Chemical Reaction
The study sought to investigate the unsteady MHD free convection flow past a vertical plate with thermal
diffusion and chemical reactions have been discussed. The dimensionless governing equations are coupled and
non-linear. These equations for this investigation are solved analytically using two-term harmonic and nonharmonic functions by perturbation technique. Approximate solutions have been derived for the velocity,
temperature field, concentration profiles, skin-friction and rate of heat transfer. The obtained results are
discussed with the help of graphs to observe that the effect of various parameter like Grashof number (Gr),
modified Grashof number (Gc), Schmidt number (Sc), Prandtl number (Pr), magnetic parameter (M), chemical
reaction parameter(k), Sorret number (So) and heat absorption parameter(ϕ).
