Abstract
The inclusion of small nano-sized particles in a pure fluid changes the material properties of the resulting mixture, called a nanofluid, significantly. To understand the role of material particles on the convection process one needs an efficient modeling of the nanofluid. The homogeneous modeling is observed to underpredict the rate of heat transfer. This fact motivates the utilization of non-homogeneous modeling. In this study we considered the classical Sakiadis moving plate boundary layer flow of a nanofluid. Non-homogeneous concentration, which is a consequence of convective transport of nanoparticles within the boundary layer, has been utilized to calculate the heat transfer enhancement. Effects of different physical parameters have been investigated on the expedition of heat transfer phenomena. It is noted that significant increase in the rate of heat transfer is observed when the nanoparticle concentration is non-uniform across the boundary layer.
