Article Title: Diffusion Thermo Effects on MHD Convective Flow Past a Semi-Infinite Vertical Moving Plate Embedded in a Porous Medium in the Presence of Chemical Reaction, Radiation and Heat Source
by P.Jyothi, N.Chaturvedi, G. Viswanatha Reddy, and P.Lalitha

Abstract:
The study of MHD flow in a porous medium is receiving worldwide attention because of its numerous applications in cooling of electronic systems, chemical catalytic reactors and thermal insulating engineering etc. The study of radiation heat transfer is very useful in nuclear power plants, missile satellites and space vehicles. In the present work the free convection heat and mass transfer flow of a Newtonian, viscous electrically conducting and heat generation/absorption fluid over a continuously vertical permeable surface in the presence of radiation, a first order homogeneous chemical reaction and Dufour effect have been studied.. The governing equations of motion have been solved by Perturbation technique. Graphical results for velocity, temperature and concentration profiles of both phases based on the analytical solutions are presented and discussed. The results show that the concentration decreases as the Schimdt number Sc increases. Velocity within the boundary layer is observed to decrease as the chemical reaction ? increases and it increases with an increase in the values of Heat parameter S. Increment in the thermal radiation parameter N and the magnetic field parameter M result in reduction of velocity. It has also been deduced that as the Radiation parameter increases, the skin friction decreases and the Nusselt number increases.
Keywords: heat and mass transfer, chemical reaction, dufour number, skin friction, magnetohydodynamic (mhd) and thermal diffusion
