Summary:

The research introduces the thermal properties of silicon dioxide (SiO2) nanofluids and the promising application of these fluids in hybrid vehicle cooling systems. How to make fluids is simply to disperse a 50-50 mixture of both Ethylene Glycol and Water; into this solution add SiO2 nanoparticles concentration ranges from 0.1% up to 0.5% volume according desired properties or material characteristics et cetera When viscosities and thermal conductivities of nanofluid were measured over the temperature range from 25 to 120 °C using Brookfield viscometer and transient hot-wire method; results were as follows: Viscosity of SiO2 nanofluids at 120°C higher concentrations 0.5%, more viscous fluids, thermal conductivity also rose with results, although there was a plateau at around 40% increase compared to that of water-based slurries. At 0.5% concentration, thermal conductivity increased by up to 20% at 120 °C, compared with the value of pure ethylene glycol. These results suggest that SiO2 nanofluids can be used to improve heat transport for hybrid vehicle cooling systems and, importantly, they provide a compromise between higher thermal conductivities (although not so great as pure water or silver sloan) and manageable viscosity increases
