SORET AND DUFOUR EFFECTS ON MHD FLOW WITH HEAT AND MASS TRANSFER PAST AN EXPONENTIALLY STRETCHING SHEET

Abstract

The current study aims to explore the impact of Soret and Dufour effects past a stretching surface with heat and mass transfer on MHD fluid flow including the effects of heat sink and radiation. Similarity transformations are employed to deduce the governing partial differential equations of flow, heat and mass transfer to system of nonlinear ODE’s. The equations together with boundary conditions so obtained are solved using numerical technique by employing Matlab’s solver bvp4c. The graph of fluid velocity, temperature and concentration distributions are obtained for different parameters for the deep analysis of the problem. It is observed that Soret and Dufour effects show notable contribution towards heat and mass transfer where the latter boosts the rate of mass transfer, and the former raises the heat transfer rate. The accuracy of the numerical solution is confirmed by comparing our results with the outcomes of previous work on stretching sheet and the results show good agreement.
