Study on MHD Free Convection Heat and Mass Transfer Flow past a Vertical Plate in the Presence of Hall Current
A two-dimensional MHD free convection heat and mass transfer flow of viscous, incompressible
and electrically conducting fluid past a vertical flat plate embedded in porous medium in the presence of hall
current under the influence of uniform magnetic field applied normal to the flow is studied analytically. In this
research work, we make the governing equations dimensionless by usual non-dimensional variables and we
obtained a set of ordinary differential equations. Then these obtained ordinary differential equations are solved
analytically by using perturbation technique. The expressions for velocity field, temperature distribution,
concentration field, skin friction, the rate of heat transfer and the rate of mass transfer are derived. Finally the
results are discussed in detailed with the help of graphs and tables to observe the effect of different parameters
like Magnetic parameter (M), radiation parameter (F), Grashof number (Gr), modified Grashof number (Gm),
Prandtl number (Pr), permeability parameter (k), Eckert number (Ec) and the chemical reaction parameter
(Kc).
