The present work is devoted to the numerical study of the effect of Heat absorption and thermal diffusion on an unsteady magnetohydrodynamic(MHD) flow of a viscous incompressible and electrically conducting fluid past along a porous flat plate taking in to account Viscous dissipation. The governing equations and the associated boundary conditions for this analysis are made non dimensional forms using dimensionless variables. The governing equations are solved numerically by using Galerkin finite element method. The flow phenomenon has been characterized with the help of parameters such as Hartmann number , Grashof number and Modified Grashof number , Schmidt Number , Prandtl Number , Eckert number , Soret number and Heat absorption . The effect of all such parameters on the fluid velocity, temperature, concentration field, the skin ? friction, the rate of heat and mass transfer have been examined and presented graphically and discussed qualitatively.
