Here magnetohydrodynamic (MHD) flow of second grade nanofluid over a nonlinear stretching surface with the convective surface boundary condition is examined. Heat and mass transfer characteristics subject to viscous dissipation, Brownian motion and thermophoresis effects are examined. Second grade fluid is electrically conducted in the presence of non-uniformly applied magnetic field. Mathematical formulation for boundary layer and low magnetic Reynolds number assumptions is presented. Newly proposed condition having a zero nanoparticles mass flux at the surface is employed. The partial differential system has been converted into the nonlinear ordinary differential system by using appropriate transformations. The resulting nonlinear system has been solved via convergent approach. Graphs are sketched to analyze the impacts of various physical parameters on the velocity, temperature and nanoparticles concentration distributions. Numerical values of skin friction coefficient and local Nusselt number are computed and discussed. (C) 2016 The Society of Powder Technology Japan.
