Thermal diffusion effect on MHD free convective and mass transfer flow in a rotating porous medium with hall current and wall temperature oscillation

An analytical study is performed to examine the thermal diffusion characteristics on the MHD free convective and mass transfer flow of an electrically conducting and viscous incompressible fluid through rotating porous medium under the action of transverse magnetic field when i) suction velocity normal to the plate is constant; ii) plate temperature varies with time about non-zero constant mean; iii) fluid is subjected to a constant heat source; iv) Hall current is taken into account. Approximate solution for velocity field are evaluated. The effects of S (thermal diffusion parameter), α (heat source parameter) and R (rotation parameter) on primary (u) and secondary velocity (v) are discussed with help of graphs.
