INDUCED MAGNETIC FIELD AND RADIATION ABSORPTION EFFECTS ON MHD FREE CONVECTIVE CHEMICALLY REACTING FLUID FLOW

This study is focused on the investigation of magneto hydrodynamic mixed convection radiative heat and mass transfer flow of a steady, viscous, incompressible electrically conducting Newtonian fluid which is an optically thin gray gas over a permeable vertical infinite plate in the presence of first order chemical reaction, temperature gradient heat source, induced magnetic field and magnetic Prandll number. The governing equations for this flow model are fommlated and solved using perturbation technique. The velocity, temperature, concentration and induced magnetic field are studied through graphs, and the skin friction coefficient, Nusselt number and Sherwood number are discussed through tables in detail for different values of physical parameters entering into the problem. It is found that the induced magnetic field increase with magnetic Prandtl number, thermal Grashof number and solutal Grashof number but decrease with thermal radiation, temperature gradient heat source, radiation absorption parameter, Schmidt number and chemical reaction parameter.
