Abstract: Nanofluid research is focused on two specific areas of testing: synthesizing new nanofluids with enhanced thermal properties, and finding new applications for nanofluids. Nanofluids are conventional heat transfer fluids with suspensions of thermally conductive nanoparticles. In this study, TiO2 (titanium dioxide) nanoparticles are used to enhance the base fluid propylene glycol (PG). The Thermal Constants Analyzer measured the thermal conductivity of the TiO2/PG nanofluid using the transient plane source (TPS) method. The measurements were recorded between 20-80 °C, and for volume concentrations of 0.1% and 0.5%. Results showed that the thermal conductivity of the solution increased with nanofluid concentration and temperature, indicating that TiO2/PG nanofluids would be effective heat transfer fluids for commercial applications.
