Abstract

Magnetohydrodynamic mixed convection boundary layer flow of heat and mass trans-
fer stagnation-point flow of a non-Newtonian power-law nanofluid towards a stretching surface in
the presence of thermal radiation is investigated numerically. The non-Newtonian nanofluid model
incorporates the effects of Brownian motion and thermophoresis. The basic transport equations are
made dimensionless first and the coupled non linear differential equations are solved by finite element
method. The numerical calculations for velocity, temperature and concentration profiles for different
values of the physical parameters presented graphically and discussed. As well as for skin friction
coefficient, local Nusselt and Sherwood numbers exhibited and examined.
