Abstract: 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 Hot Disk Thermal Constants Analyser TPS 500. Samples were tested between 10 °C and 50 °C, increasing by 10 °C each trial, and 10 replicates were performed at each time point. Test results showed that temperature and thermal conductivity of cyclohexane-based nanofluids are inversely related. As the temperature increased, thermal conductivity decreased in a relatively linear trend, with a more pronounced enhancement in thermal conductivity for solutions with a higher concentration of particles.
