Abstract
In this paper, we discuss Diffusion-thermo and Thermo-diffusion effects on MHD free convective incompressible, Newtonian fluid flow over non linearly stretching sheet with radiation and chemical reaction, through a non-Darcy porous medium. By suitable similarity transformations, the boundary layer equations are transformed to ordinary differential equations. The method, numerical computation with bvp4c (a MATLAB program) is used to solve these equations. The effects of Magnetic parameter, Diffusion -thermo number and Thermo-diffusion number on velocity profiles, heat and mass transfer, Skin-frictions, Nusselt Number and Sherwood Number are computed, discussed and analysed numerically and presented through tables and graphs.
Keywords: MHD flow, magnetic parameter, diffusion-thermo number, thermo-diffusion number
