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 (...
Silver (Ag) has the highest thermal conductivity of all metals, making it an attractive nanoparticle for use in heat transfer systems. The shape of nanoparticles influences their thermal conductivity, so three varieties of Ag nanoparticles were tested in this study. The Thermal Constants Analyser measured the thermal conductivity of Ag nanospheres (NSs), nanowires (NWs), and nanoflakes (NFs) between 10-30 °C using the transient plane source (TPS) method. Results showed that ...
The addition of thermally conductive nanoparticles to conventional heat transfer fluids enhances their performance so they can be used for high-powered applications. However, as nanoparticles are added, the liquid becomes more viscous, which decreases thermal conductivity. Changing the pH of the solution can control the clustering of nanoparticles to maintain and even enhance thermal conductivity. This study used the transient plane source (TPS) method to measure the thermal conductivity of ...
Many studies have been conducted on nanofluids with bases of water and ethylene glycol. Cyclic alkane, more commonly known as cyclohexane, can be used as the base liquid for cold storage, however minimal research has been conducted with these solutions. This study explores the temperature-dependent thermal conductivity of cyclohexane with copper oxide nanoparticles. Thermal conductivity was measured using the Thermal Constants Analyser. Samples were tested between 10 °C and 50 °C, increasing ...
