The purpose of this study was to measure the thermal conductivity of cementitious Kaolite 1600 for its potential to replace the radioactive materials in ES-2 containers. A thermal constants analyzer measured the thermal conductivity of the Kaolite samples using the transient plane source (TPS) method. Results showed that despite different densities, the thermal conductivities of the samples were similar up to 100 °C. Similar to ceramics and other insulating materials, the thermal ...
In this study, multi-walled carbon nanotubes (MWCNTs) were added to Al2O3/water nanofluids to determine their heat transfer and temperature drop properties compared to water and Al2O3/water nanofluids. A TPS thermal constants analyzer measured the thermal conductivity of the Al2O3/water nanofluids using the transient plane source (TPS) method. The thermal conductivity of Al2O3/water nanofluids was further enhanced with the addition of MWCNTs because ...
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 ...
The application of carbon nanotubes (CNT) to thermal management devices has recently drawn much attention. This study produced and examined metal-carbon nanotube composites for use in highly conductive yet stable thermal management materials. The structural and thermophysical properties of metal-CNT composites were examined, including the measurement of thermal conductivity using the Thermal Constants Analyzer TPS transient plane source (TPS) method. Results showed that generally, inverse relationships were observed between thermal ...
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 ...
