摘要：

In this paper, we study the unsteady coupled heat and mass transfer of two-dimensional MHD fluid over a moving oscillatory stretching surface with Soret and Dufour efects. Viscous dissipation efects are adopted in the energy equation. A uniform magnetic field is applied vertically to the flow direction. The governing equations are reduced to non-linear coupled partial diferential equations and solved by means of homotopy analysis method(HAM).The efects of some physical parameters such as magnetic parameter, Dufour number, Soret number, the Prandtl number and the ratio of the oscillation frequency of the sheet to its stretching rate on the flow and heat transfer characteristics are illustrated and analyzed.
