AN OSCILLATORY THREE DIMENSIONAL FLOW PAST AN INFINITE VERTICAL POROUS PLATE WITH SORET AND DUFOUR EFFECTS

The problem of an oscillatory three dimensional flow past an infinite vertical porous plate with Soret and Dufour effects is presented. Analytical solutions to the coupled non-linear equations governing the flow and heat and mass transfer are solved by regular perturbation technique. The expression for the velocity field, temperature field, species concentration, the Skin-friction, Nusselt number and Sherwood number at the plate are obtained in non-dimensional forms. The velocity distribution, temperature, chemical species concentration, Coefficient of Skin-friction, Nusselt number and Sherwood number at the plate are demonstrated graphically and the effects of different parameters viz. the Suction Reynolds number, the Grashof numbers, the Soret number and the Dufour number on these fields are discussed
