MHD Flow and the Characteristics of Heat and Mass Transfer Past an Exponential Stretching Sheet with Heat Source/Sink

Abstract

In this paper, we analyzed the effect of a suction and Soret number on heat and mass transfer MHD flow past an exponentially stretching sheet with the heat source/sink. Using similarity transformation the system of PDEs is changed into a system of non-linear ODEs, which was then solved numerically by Runga kutta fourth order method together with shooting technique. The Numerical results are obtained for the skin friction coefficient, Nusselt and Sherwood numbers for selected values of the governing parameters, such as the suction, magnetic field parameter , viscous dissipation parameter , heat generation parameter , Schmidt number , and the chemical reaction rate parameter . Besides, it is obtained that the concentration profile decreases with an increment of the Schmidt number. A comparison was made with a previous study available in the literature and we found that it is in a good agreement.
