The objective of this experimental study is to study the effects of a hybrid utilization of graphene oxide (GO) and titanium oxide (TiO2) nano-materials on the water thermal-conductivity. The experiments were carried out for different concentrations of 0.05, 0.1, 0.2, 0.4, 0.6, 0.8 and 1% and in the temperature range of 20 to 50 degrees C. The experiments showed that higher temperature and concentrations of nano-materials result in a higher the thermal-conductivity. The maximum thermal-conductivity enhancement was 32.8%. Moreover, a new accurate correlation for the thermal-conductivity was presented based on the experimental data obtained in the laboratory in terms of temperature and nano-materials volume fraction.
