Abstract


The aim of this research paper is to study the combined effects of Soret, Dufour on an unsteady MHD flow past an infinite vertical plate in a porous medium with variable temperature and mass diffusion in presence of chemical reaction. The momentum, energy, and concentration equations derived as coupled second-order, ordinary differential equations and are solved numerically using a highly accurate and thoroughly tested finite element method (FEM). The effects of Soret number, Dufour number, Grashof number for heat and mass transfer, Schmidt number, Chemical reaction parameter, Prandtl number and Permeability parameter on the dimensionless velocity, temperature and concentration profiles are presented graphically. In addition the local values of the Skin –friction coefficient, Nusselt number and Sherwood number are also shown in tabular form. The discussion focuses on the physical interpretation of the results as well their comparison with the results of previous studies
