EFFECT OF CHEMICAL REACTION ON MHD FLOW PAST AN OSCILLATING INFINITE VERTICAL PLATE EMBEDDED IN POROUS MEDIUM IN THE PRESENCE OF HEAT SINK

An analytical investigation is presented to examine the influence of heat sink and chemical reaction on heat and mass transfer flow past an oscillating vertical plate embedded in porous medium in the presence magnetic field. A uniform magnetic field of uniform strength B-o is applied normal to the main flow direction. The resulting non linear coupled partial differential equations for the velocity, temperature and concentration fields with the boundary conditions are reduced to non dimensional form. The governing equations are solved in closed form by adopting the Laplace transform technique and obtained the solutions of velocity, temperature and concentration fields. The effects of the physical parameters such as magnetic parameter, thermal Grashof number, solutal Grashof number, permeability parameter, Prandtl number, Schmidt number, heat sink and chemical reaction involved in the flow problem and the transport characteristics are examined with the help different graphs.
