Unsteady MHD Convective Heat And Mass Transfer Past An Infinite Vertical Plate Embedded In A Porous Medium With Radiation And Chemical Reaction Under The Influence Of Dufour And Soret Effects

摘要

A two-dimensional unsteady MHD free convective heat and mass transfer flow past a semi-infinite vertical porous plate in a porous medium in presence of thermal radiation and chemical reaction has been studied numerically including the Dufour and Soret effects. The governing nonlinear partial differential equations have been reduced to the coupled nonlinear ordinary differential equations by the similarity transformations. The resulting equations are then solved numerically using shooting method along with Runge-Kutta fourth order integration scheme. The numerical results are displayed graphically showing the effects of various parameters entering into the problem. Finally, the local values of the skin-friction coefficient, Nusselt number and Sherwood number are also shown in tabular form.
