dc.description.abstractIn this study; enhancement of heat transfer on a high heat-flux surface is investigated numerically by using nanofluids with impinging jet technique. Heat transfer from flat copper surface was studied for different Reynolds number (Re=12000, 14000, 16000, 18000), different particle diameter of nanofluid (Dp=10nm, 20nm, 40nm, 80nm), different volume fraction of nanofluid (phi=% 2, % 4, % 6, % 8), and different types of nanofluids (CuO-water, NiO-water, Cu-water, pure water). The low Reynolds number k-e turbulence model of the PHOENICS CFD program was used in the study. As a result; increasing Re number from 12000 to 18000 resulted in an increase of 28% on average Nusselt number. It has been obtained that decreasing particle diameter from 80nm to 10nm causes an increase of 13.20% on average Nusselt number. It has been determined that increasing volume ration more than 4% does not cause a significant increase in heat transfer. In the case of using different types of nanofluids, the best heat transfer performance is obtained when Cuwater nanofluid is used. Using Cu-water nanofluid showed an enhancement of 8.3% on average Nusselt number compared to pure water. Moreover; it has been shown that the low Reynolds number k-epsilon turbulence model can well represent the temperature distribution and flow properties.
