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 ...
Smouldering combustion is a slow, low-temperature form of combustion that is used to improve soil health. Extensive research has yet to be completed about smouldering liquid hydrocarbons in a stationary porous medium such as coal tar in sand. This study examined heat transfer in sand under simulated smouldering combustion conditions. The Thermal Constants Analyser was used to measure the thermal conductivity, thermal diffusivity and specific heat of sand at heightened ...
H2O/KCOOH (potassium formate) is a highly soluble hygroscopic salt solution that has the potential to be used as a desiccant. However, the thermophysical properties of H2O/KCOOH are only available for concentrations between 20-50%, which is not beneficial for their use as dehumidifiers. In this paper, a TPS system was used to measure the thermal conductivity of H2O/KCOOH solution with salt concentrations of 60-80% between 1 °...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
Quad Flat Non-Lead (QFN) devices are sensors used in building designs to control electronic equipment. The temperature of the QFN sometimes exceeds its maximum threshold, which this is primarily due to the encapsulating resin. In this study, the thermal conductivity of the resin was tested for the QFN16b, QFN32b, and QFN64b using the Transient Plane Source (TPS). Power levels between 0.1 W and 1.0 W were administered through the ...
