    a study has been carried out to analyze the effects of variable thermal conductivity, soret (thermal-diffusion) and dufour (diffusion-thermo) on mhd non-darcy mixed convection heat and mass transfer over a non-linear stretching sheet embedded in a saturated porous medium in the presence of thermal radiation, viscous dissipation, non-uniform heat source/sink and first-order chemical reaction. the governing differential equations transform into a set of non-linear coupled ordinary differential equations using similarity analysis. similarity equations are then solved numerically using shooting algorithm with runge–kutta fehlberg integration scheme over the entire range of physical parameters. a comparison with previously published work has been carried out and the results are found to be in good agreement. graphical presentation of the local skin-friction coefficient, the local nusselt number and the local sherwood number as well as the temperature profiles show interesting features of the physical parameters.
