In this paper, we investigate the combined influence of Heat source, Soret and Dufour effects on transient convective heat and mass transfer flow of a micro polar fluid through porous medium past permeable stretching sheet in slip flow regime with constant heat and mass flux. The non linear coupled equations governing the flow heat and mass transfer flow have been solved by Employing Galerkin finite element technique with quadratic approximation polynomials. The velocity, microrotation, temperature and concentration have been discussed for governing parameters. The skin friction, the rate of heat and mass transfer have evaluated numerically for different parametric variations.
