Abstract
In this paper, the thermo-diffusion and Diffusion-thermo effects on MHD micropolar fluid flow over a linearly stretching sheet, through a non -Darcy porous medium, where stretching velocity of the sheet varies linearly with distance from the origin, and, temperature and concentration vary non linearly in the boundary layer region, is discussed. By suitable similarity transformations, the governing boundary layer equations are transformed to ordinary differential equations and to solve these equations the method applied is numerical computation with bvp4c, a MATLAB program. The effects of Magnetic Parameter, Soret number and Dufour number on velocity profiles, microrotation profile, heat transfer, and concentration, Skin- Frictions, local Nusselt Number and local Sherwood Number are computed, discussed and analysed numerically and presented through tables and graphs.
Keywords: MHD Flow, magnetic parameter, Dufour number, soret number.
