Raju Journal on Future Engineering and Technology 2230 – 7184 7 4 11 20 Chemical reaction, Radiation, MHD, Porous Media In this paper a mathematical model is presented for an unsteady flow of a viscous, incompressible, electrically conducting, and laminar, free convective boundary layer flow of a continuously moving infinite vertical plate in a radiative and chemically reactive medium in the presence of a transverse magnetic field. The governing equations are solved by the method of Laplace transform technique and the expressions for velocity, temperature, and concentration have been obtained. The derived parameters such as skin friction, rate of heat transfer in the form of Nusselt number and the rate of mass transfer in the form of Sherwood number using the basic parameters, and Further, the effects of various physical parameters like magnetic parameter M, Grashof number Gr, modified Grashof number Gm, heat source parameter H, the chemical reaction parameter Kc, Schmidt number and Radiation parameter F on fluid flow are studied through graphs.
