Numerical analysis of nanofluid transport over a stretching surface with variable thermal conductivity, brownian motion and thermophoretic effects

This paper presents a numerical investigation of nanofluid boundary layer flow over a linearly stretching sheet in the presence of variable thermal conductivity, thermophoretic diffusion and Brownian motion. Unlike earlier treatments, which examine these mechanisms individually or in pairs and usually alongside magnetic, radiative or chemically reactive effects, the three are treated here simultaneously and in isolation, so that their interaction can be identified without confounding.
