The current work examines the mixed action of Soret and Dufour effects, melting and chemical reaction on stagnation point flow of micropolar fluid on a stretching sheet in a porous medium. Suitable non-dimensional transformations are adopted to transform the governing equations of flow, heat and mass transfer to dimensionless form. Bvp4c numerical scheme is applied to acquire the result numerically in graphical form for velocity, microrotation, temperature and concentration distributions. The accuracy of the solution has been verified by making comparison with already published work. Numerical values are computed for coefficient of skin-friction, couple stress, Nusselt number and Sherwood number for important parameters to get a deeper insight of the impact of dimensionless shear stress at the surface, heat and mass transmission process. The study discloses the fact that the combined effect of Soret and Dufour hike the fluid temperature but reduces the concentration.
