Abstract

This article studies the Soret and Dufour effects on unsteady MHD free flow of Casson fluid over a vertical plate with a constant wall temperature. The fluid is electrically conducting and passing through the porous medium. The governing nonlinear partial differential equations have been reduced to the coupled nonlinear ordinary differential equations by the similarity transformations. The governing equations are solved numerically using MATLAB bvp4c routine and presented through graphs. The numerical values of skin-friction coefficient and Nusselt number are derived, discussed numerically for various values of physical parameters and presented through tables.
