In this paper, we analyse the thermo diffusion and diffusion thermo effects on MHD Casson fluid flow over a linear/nonlinear stretching sheet. By making use of appropriate similarity transformations, the governing equations of the flow are reduced into a set of nonlinear coupled ordinary differential equations. Further, these equations are solved numerically using Runge-Kutta based shooting technique. The effect of pertinent parameters on velocity, temperature and concentration profiles along with friction factors, local Nusselt and Sherwood numbers are discussed and presented with the help of graphs and tables. From the results, we found that heat transfer performance on the flow over a nonlinear stretching surface is higher than that of the flow over a linear stretching surface.
