Abstract

This article is confined to study the effects of radiation, Soret and Dufour on unsteady double diffusive flow of a chemically reacting fluid over a vertical porous plate in fluctuating temperature and mass diffusion in the presence of heat source. A magnetic field is applied normal to the flow. Roseland approximation is used to describe the radiative heat flux in the energy equation. The governing equations in non-dimensional form are solved numerically, using implicit finite difference method, for which numerical code is executed using C-Program. The results obtained for velocity, temperature and concentration are discussed and analyzed graphically. It is observed that the velocity and the solutal boundary layer thickness increase for increasing values of Soret number. It is also observed that velocity and the thermal boundary layer thickness enhance for increasing values of the Dufour number. The results of the validation of this work in the absence of heat source and viscous dissipation parameters agree significantly with previous work.

Keywords: Double diffusive fluid, rotation, MHD, porous medium, radiation, Implicit –finite difference method
