Abstract


This paper studies the combined effects of Soret (thermal-diffusion) and Dufour (diffusion-thermo) on MHD boundary layer flow of a Jeffrey fluid past a stretching surface with chemical reaction and heat source. Using the similarity transformations, the governing equations are transformed into a set of non-linear ordinary differential equations. The resulting equations are then solved numerically by using the shooting method along with Runge-Kutta fourth order integration scheme. Numerical results for the velocity, temperature and concentration distributions as well as the skin-friction coefficient, Nusselt number and Sherwood number are discussed in detail and displayed graphically for various physical parameters. The results indicate that the influence of Soret and Dufour numbers are significantly active in the study of non- Newtonian fluid flows. The accuracy of the numerical method is tested by comparing with previously published work in the limiting case (for viscous flow) and the results are found to be in excellent agreement.
