Abstract: “In this paper, numerical method is developed and simulations of flow and heat transfer of nanofluids is presented. The effect of nanoparticle volume fraction for the enhancement of heat transfer is examined for several sets of values of Reynolds numbers. The study is conducted for pure water and watercopper nanofliud. The study is carried out for Reynolds numbers of 100 and 150 and for volume fraction of nanoparticles of 0, 0.05, 0.10 and 0.15. The mean Nusselt numbers for front and rear cylinders are obtained. The obtained results indicated that the increase of nanoparticles volume fraction has a positive effect on the mean Nusselt number.”
