JMAT_V4_N3_RP4 J. Girish Kumar Journal on Mathematics 2277-5137 4 3 35 48 Magnetohydrodynamics (MHD), Oscillatory Flow, Porous Medium, Heat Generation, Radiation Free convective oscillatory mass transfer flow past an infinite vertical porous plate with heat and mass fluxes in the presence of uniform magnetic field and heat generation through porous medium is analytically investigated. Effects of radiation and viscous dissipation on the unsteady two-dimensional flow of a viscous incompressible, electrically conducting with optical thin gray fluid are considered. Approximate solutions have been derived from the velocity, temperature and concertation fields, coefficient of skin-friction, Nusselt number and Sherwood number using multi-parameter perturbation technique. It is observed that the increase in radiation parameter decreases the both velocity and temperature. July - September 2015 Copyright © 2015 i-manager publications.
