Abstract
A boundary layer analysis that has been presented for the heat and mass transfer in power-law nanofluids over a stretching surface with convective boundary condition are investigated numerically. The surface nanoparticle concentration is kept constant. A power-law model is used for non-Newtonian fluids, whereas Brownian motion and thermophoresis effects are incorporated in the nanofluid model. A similarity transformation is used to reduce mass, momentum, thermal energy, and nanoparticles concentration equations into nonlinear ordinary differential equations which are solved numerically by using a finite difference method. The effects of nanofluid parameters, suction/injection, and convective parameters and generalized Pr and Le numbers on dimensionless functions, skin friction, local Nusselt, and Sherwood numbers are shown graphically. The quantitative comparison of skin friction and heat transfer rates with the published results for special cases is shown in tabular form and is found in good agreement.
