Soret-Dufour Effect on Variable Viscosity MHD Flow Through Porous Medium

In this paper we have explored the Soret and Dufour effects on unsteady viscous incompressible and electrically conducting MHD flow through porous medium past an inclined infinite plate with variable viscosity fluid and periodic suction or injection of fluid through the plate with exponential increment in temperature and exponentially decrement in concentration. The developed or governing physical model of the flow field has been converted into the mathematical model. Then mathematical model of system of equations is represented by set of governing non linear partial differential equations which have been non dimensionalized by the help of non dimensional numbers. The associated dimensionless governing equation of flow field is solved numerically by Crank Nicolson finite difference implicit method for different values of governing flow parameters. The effects of various responsible flow parameters have been discussed through graphs and table. The effects and their numerical corresponding variations have been concord with physical nature of the problem. The velocity profile, concentration profile and temperature profile are shown through graphs for different values of flow parameters. The obtained numerical values of the skin friction, Nusselt number and Sherwood number with their variations for different values of flow parameters have been tabulated.
