A small book of MHD free convection heat and mass transfer flow
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).
