Abstract: A numerical study of Soret and Dufour effects on MHD free convective
heat and mass transfer unsteady high speed flow of viscous fluid through a
porous medium with induced magnetic field is investigated in a rotating system.
In this observation, heat and mass fluxes from the medium are considered to be
constant for cooling problem with lighter and heavier particles. Numerical
values of velocity, induced magnetic field, temperature and concentration are
computed by the conditionally stable explicit finite difference method with
stability and convergence analysis. The shear stress, current density, Nusselt
number and Sherwood number are also calculated here. Effects of associated
parameters on the above mentioned quantities are shown graphically and physical
aspects of the problem are discussed in detail. Finally, both the qualitative
and quantitative comparisons of present results with previous work are
presented in tabular form.
