This research demonstrates enhanced thermal conductivity and viscosity in nanofluids, suggesting improved heat transfer performance.
In recent years, research focused on enhancing the thermo-physical properties of a single component nanofluid. Therefore, hybrid or composite nanofluids are developed to improve heat transfer performance. The thermo-physical properties of the Al2O3-TiO2-SiO2 nanoparticles suspended in the base of water (W) and ethylene glycol (EG) blends with vol 60:40, many volume concentrations are investigated. The experiment was conducted for the concentration volume of 0.05, 0.1, 0.2 and 0.3% of Al2O3-TiO2-SiO2 nanofluids with temperature conditions of 30, 40, 50, 60 and 70 °C. The development of new correlation for thermal conductivity and dynamic viscosity of tri-hybrid nanofluids have been found to be precise. As a conclusion, the combination of enhancement in thermal conductivity and a dynamic viscosity at a concentration of 0.3% has optimum conditions, which have more advantages for heat transfer than other concentrations.
