A numerical study is accomplished to analyze the Brownian motion of micro-polar hydromagnetic nano-fluid over a stretched surface with thermophoresis and thermal radiation effect. The dimensional equations of the proposed model are reformed by acceptable similarity transformations and the numerical approach using MATLAB in connection with bvp4c is implemented to solve the final equations. The convergence, salient features of the pertinent parameters on micro-polar nano-fluid flow for velocity, angular velocity, temperature and concentration are emphasized on the plots. We also discuss the effect on Skin friction, Nusselt number and Sherwood number and displayed via Tables. The influence of Grashof number is remarkable throughout the study. Outcomes obtained indicate that for enlarged values of micro-polar parameter, the angular velocity is raised. The validity and accuracy of the present model have been checked and found adequate agreement. The importance of such analysis over stretched sheet have numerous manufacturing, industrial and engineering applications in plastic sheets extrusion, polymer extraction, blowing of glass, manufacture of paper and rubber sheets.
