Effects of Soret and Dufour on Mixed Convection over a Cone in a Non-Darcy Porous Medium with Chemical Reaction

Abstract

This work explore the boundary layer behavior under the effects of Soret and Dufour on the mixed convection adjacent to inverted cone immersed within non-Darcian porous milieu together with chemical reaction action. The natural and forced convection limits are also considered in this study. The equations governing the problem together with the boundary conditions are converted to non-similar non-dimensional shape and solved numerically using finite difference method. It was found that enhances the value of the Soret number will increase the amount of heat transport and decrease the amount of mass transport. Enhances the value of Dufour number or chemical reaction parameter will reduce the amount of heat transfer and raise the amount of mass transfer.
