Steady magnetohydrodynamic flow in non-Newtonian nanofluid due to non-linear stretching surface

Abstract

The steady magnetohydrodynamic (MHD) flow in non-Newtonian nanofluid due to a nonlinear stretching surface with arbitrary injection/suction is studied. Similarity variables were utilized to obtain a system of nonlinear ordinary differential equations and the system was numerically by collocation method. The velocity, temperature and concentration profiles, Nusselt and Sherwood numbers of the nanofluid with various values of the physical parameters were obtained. The suction to injection increases the velocity boundary layer. The velocity boundary layers reduce while the temperature increases when the magnetic field were applied. The Brownian motion increased the temperature boundary layers but it reduces the concentration boundary layers. It was found that a higher value of thermophoresis parameter will increase the temperature and concentration boundary layers of the nanofluid.
