Abstract. A study of viscous dissipation and chemical reaction effects of nanofluid flow passing over a stretched surface with the MHD stagnation point and the convective boundary condition has been analyzed numerically. The constitutive equations of the flow model are solved numerically and the impact of physical parameters concerning the flow model on dimensionless velocity, temperature and concentration are presented through graphs and tables. Also, a comparison of the obtained numerical results with the published results of W. Ibrahim has been made and found that both are in excellent agreement. As a result of the research, it was obtained that the magnetic parameter has the same increasing influence on the temperature and the concentration field but opposite on the velocity field, the temperature field, and the concentration field reduce with an increase in the Prandtl number, increase in viscous dissipation increases temperature and concentration profile, and concentration as well as the thickness of concentration decrease by increasing values of chemical reaction parameter.

Keywords: magnetohydrodynamic, stretching sheet, nanofluid, viscous dissipation, chemical reaction.
