Thermophoresis and Soret-Dufour on MHD mixed convection mass transfer over an inclined plate with non-uniform heat source/sink and chemical reaction

An analysis is presented to investigate thermophoresis and Soret-Dufour on MHD mixed convective heat and mass transfer of a semi-infinite permeable inclined flat plate in the presence of non uniform heat source/sink and chemical reaction. The governing differential equations are transformed into a set of non-linear coupled ordinary differential equations and solved using a numerical technique with appropriate boundary conditions for various physical parameters. The numerical solution for the governing nonlinear boundary value problem is based on the numerical integration scheme over the entire range of physical parameters. The effects of various physical parameters on the dimensionless velocity, temperature, and concentration profiles are depicted graphically and analyzed in detail. Favorable comparisons with previously published work on various special cases of the problem are obtained. Finally, numerical values of the physical quantities, such as local skin-friction coefficient, the local Nusselt number and the local Sherwood number are presented in tabular form.
