Abstract: The aim of this paper is to investigate the numerical study of heat and mass transfer on an unsteady MHD flow past a vertical accelerated plate considering Soret and Dufour effects. The governing nonlinear partial differential equations are solved by finite element method and the numerical results are obtained for velocity, temperature, concentration, skin friction, Nusselt number and Sherwood number. The effects of different flow parameters on the flow variables are discussed and presented through graphs and tables. Finally, the numerical results for some special cases were compared with previous results to ensure the correctness of this numerical scheme and were found to be in excellent agreement.

Keywords: Soret and Dufour effects, Chemical reaction, MHD, Heat and Mass Transfer.
