摘要：

In this paper, the convective heat transfer of nanofluid flow in a turbulent boundary layer of a flat plate is simulated numerically. Turbulent flow equations with RNG K-epsilon turbulence model are solved employing Fluent software. Furthermore, the effects of nanoparticle concentration on the heat transfer characteristics are studied. The results show that nanofluids enhance the heat transfer coefficient dramatically with little change in pressure drop.
