Abstract: The present study is carried out to examine the effects of radiation and Hall current on unsteady natural convection flow of a viscous, incompressible and electrically conducting fluid past an impulsively started inclined plate under the influence of transversely applied uniform magnetic field. The governing equations involved in the present analysis are solved by the Laplace-transform technique. The results obtained are discussed with the help of graphs drawn for different parameters like thermal Grashof number, mass Grashof number, Prandtl number, Hall current parameter, radiation parameter, magnetic field parameter and Schmidt number. The numerical values obtained for skin-friction and Nusselt number have been tabulated. The results obtained are in agreement with the actual flow phenomenon. The motive of this study is to analyze radiation and the Hall effect on the flow model. In the study, we found that the velocity in the boundary layer increases with the values of radiation and Hall current parameters. It is also observed that radiation and the Hall current increases the drag at the plate surface.

Keywords:  MHD flow, inclined plate, radiation effect, variable temperature, mass diffusion, Hall current.
