Soret and Dufour effect with hall current of a magneto hydro dynamic flow of a viscous fluid through vertical porous channel is studied here. Also studied the impacts of ramped wall temperature on the incompressible fluid. Using regular perturbation technique with boundary conditions the velocity, temperature and concentration of the fluid are calculated and it shows the velocity of the fluid increases when Soret number increases and velocity decreases with the increasing values of Dufour number. Also the variations in temperature and concentration also studied with the help of graphs. [ABSTRACT FROM AUTHOR]

From this paper analyses about mass and heat mass transfer effects along by thermal diffusion along with warm source of an oscillatory flow in a 2D, thick, electrically fluid through an infinite vertical penetrable plate with moving condition within a flooded porous medium into the occurrence of transfer attractive field and chemical reaction. Heat source and soret impacts are added into the governing equation to discuss about the velocity, temperature and concentration profile of the current problem. The series expansion method is used to get the analytical solution and the relevant results are depicted through graphs. Various non-dimensional parameters like Chemical response parameter, Prandtl number, Soret effect, magnetic field parameter and Grashof number for mass transfer are all discussed through graphs.

The aim of the present paper is to explore radiation effect with heat source on unstable natural convective MHD flow past on vertical porous plate. In perpendicular direction to the plate an uniform magnetic field will be applied. Thermal radiation effect, chemical reaction effect and soret effect are included. Reactions of various parameters on velocity, temperature and concentration are verified and analyzed through graphs. [ABSTRACT FROM AUTHOR]
