The heat generation/absorption and thermo-diffusion on an unsteady free convective MHD flow of radiating and chemically reactive second grade fluid near an infinite vertical plate through a porous medium and taking the Hall current into account have been studied. Assume that the bounding plate has a ramped temperature with a ramped surface concentration and isothermal temperature with a ramped surface concentration. The analytical solutions for the governing equations are obtained by making use of the Laplace transforms technique. The velocity, temperature, and concentration profiles are discussed through graphs. We also found that velocity, temperature, and concentration profiles in the case of ramped temperature with ramped surface concentrations are less than those of isothermal temperature with ramped surface concentrations. Also, the expressions of the skin friction, Nusselt number, and Sherwood number are obtained and represented computationally through a tabular form.

In this Paper, an investigation of the heat and mass transfer on the flow of an oscillatory convective MHD viscous incompressible, radiating and electrically conducting second grade fluid in a vertical porous rotating channel in slip flow regime and taking Hall current into account is carried out. The fluid is assumed to be gray, absorbing and emitting radiation out in non scattering medium. The MHD flow is assumed to be laminar and fully developed. A closed form solutions of the equations governing the flow are obtained for the velocity and temperature distributions making use of regular perturbation technique. The velocity, temperature and concentration profiles are discussed through graphically as well as skin friction coefficient, Nusselt number and Sherwood number are evaluated numerically and presented in the form of tables and discussed for different values of governing flow parameters.Key words: Hall Effect, radiating fluid, MHD oscillatory flow, rotating channel, slip flow regime. IntroductionThe study of flow in rotating porous channel is motivated by its practical applications in geophysics and engineering. Among the applications of rotating flow in a porous media to engineering disciplines, one can find the food processing industry, chemical processing industry, centrifugation filtration processes and rotating machinery. In engineering, it finds its application in MHD generator ion propulsion, MHD bearing, MHD pumps, MHD boundary layer control of re-entry vehicles etc. Several scholars viz. Hall effect on unsteady MHD free and forced convection flow in a porous rotating channel has been investigated by several researchers
