dc.description.abstract The numerical studies are performed to examine the MHD free convection and mass transfer flow with thermal diffusion and dufour effects past an infinite vertical porous plate. Method of Superposition and the Shooting method are used as main tools for the numerical approach. The studies of the flow feature mentioned above are made in different sections takin different aspects of the flow that are of practical importance. These studies are mainly based on the similarity approach. At first similarity solutions have been obtained for the Unsteady MHD free convection and mass transfer flow past an infinite vertical porous plate taking into account the thermal diffusion and Dufour effects. Impulsively started plate moving in its own plane is considered. Similarity equations of the corresponding momentum, energy and concentration equations are derived by introducing a time dependent length scale which infact plays the role of a similarity parameter. The suction velocity is taken to be inversely proportional to this parameter. The momentum, energy and concentration equations are solved numerically by applying the method of superposition. The above flow problem has further been considered in a steady two dimensional problem of the MHD free convection and mass transfer flow past an infinite vertical porous plate taking into account the Soret and Dufour effects. The similarity solutions of the governing equations are obtained by employing the usual similarity technique based on large suction. The effects on the velocity. Temperature, concentration, skin-friction, Nusselt number and the Sherwood number of the various important parameters entering into the problems separately are discussed for each problem with the help of graphs and tables. Finally, a general discussion o n t he overall solutions o f the problems considcred in t lie dissertation are sorted out. en_US
