Özet

The cooling performance of a vehicle radiator was experimentally investigated using pure water, graphene oxide (GO) and graphene nano ribon (GNR) nano-fluids in this paper. Three different fluid inlet temperatures (36, 40 and 44 °C) and four different flow rates (0.6, 0.7, 0.8 and 0.9 m3 h−1 ) were performed in the experiments. GO and GNR nano-fluids were obtained at 0.01 and 0.02% vol. concentrations by means of pure water as a base fluid. In order to determine the heat transfer enhancement, the experimental datas were compared as overall heat transfer coefficients (U) for pure water and nano-fluids. The mean enhancement values of U for all temperatures were obtained as 5.41% and 26.08% for 0.01% and 0.02% vol. concentrations of GO/water nano-fluid and 15.62% and 20.64% for 0.01% and 0.02% vol. concentrations of GNR/water nano-fluid, respectively
