Two phase boundary layer nanofluid flow and heat transfer analysis over a stretching sheet: A realistic approach

The problem of boundary layer flow of nanofluid over the stretching sheet with zero nanoparticle flux at boundaries has been investigated numerically. The present paper is revision of earlier published paper of Khan and Pop1 by taking passively controlled nanofluid particle volume concentration at the boundaries. The Buongiorno's nanofluid model incorporating Brownian motion and thermophoresis effect is now possible to apply in reality for the plate problems. The multiple regression estimations for heat transfer analysis have also been conducted for the feasible range of all the significant parameters. The Brownian motion is found to have negligible effect on reduced Nusselt number. The reduced Nusselt number is decreasing function of thermophoresis parameter Nt and Lewis number Le.
