Thermocells are heat waste harvesting devices that operate at room temperature. The addition of multi-walled carbon nanotubes (MWCNTs) to ionic liquids (ILs) in thermocells enhances electrical conductivity, and the devices can operate at higher temperatures. In this study, various properties of ILs containing MWCNTs were examined, and a TPS system measured the thermal conductivities of the samples using the transient plane source (TPS) method. Results showed that the thermal conductivity ...
Nanofluids are heat transfer fluids with enhanced thermal conductivity properties due to the addition of metallic-based nanoparticles. In this study, the thermal properties of Al¬2O3 and TiO2 nanofluids were examined to evaluate their usefulness in microchannel heat sink applications. A thermal constants analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that thermal conductivity increased with volume fraction of nanofluids, and ...
Metal foams are materials composed of a solid grid with air-filled pores, and have applications in combustion chambers of gas turbines. In this study, the thermal properties of porous metal foams were tested to determine their usefulness in heating and cooling systems. The Transient Plane Source (TPS) method was used to measure the thermal conductivity of porous metallic foams. Because the porous foams were not as compacted as the dense ...
Nanofluids are used to improve the thermal conductivity of heat transfer fluids. This study examined the effects on thermal conductivity of zinc oxide (ZnO)/ethylene glycol + water nanofluids as increasing concentrations of ZnO nanopartilces were added to the solution. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the nanofluids using the Transient Plane Source (TPS) method. As expected, the thermal conductivities of the solutions increased with nanoparticle concentration, ...
The expanding production of polymeric materials is causing plastic waste to become a growing concern. This study aimed to fabricate cement and mortar composites that contained plastic in an attempt to extend the life of non-reusable plastics. The thermal conductivity of the composite material was measured using the transient plane source (TPS) technique. Results showed that as expected, thermal conductivity decreased as the plastic content in cement and mortar composites ...
