This research investigates the core materials used to create vacuum insulation panels. Of particular interest to the investigators was the thermal conductivity of the initial materials (usually powders) under different pressures. The researchers designed their own powder sample cell holder. The powders tested were low density silica powders, and using the sample set up the team was able to test them along a pressure range from atmospheric pressure to 0.1mbar. ...
This article describes comprehensive testing performed to increase understanding of how the thermal conductivity of ceramic fibers is affected. Non fibrous material content, temperature, and pressure were the main parameters investigated. Three different ceramic fiber samples were used in the research. Researchers discovered that the incorporation of aluminum reduced the thermal conductivity and consequently improved the insulation performance of the sample. An increase in pressure increased the thermal conductivity of ...
The thermal conductivities of gas hydrates are well documented, but the thermal conductivities of structure H (sH) methane-methylcyclohexane (MCH) hydrate and type A tetrabutylammonium bromide (TBAB) semi clathrate hydrate have no experimental data. The purpose of this study was to determine the thermal conductivities of sH MCH hydrate and TBAB semi clathrate hydrate. The thermal conductivity was measured using a single sided transient plane source (TPS) method. Most gas hydrates ...
The purpose of this study was to analyze the thermal properties of metal hydride for its application in hydrogen storage systems. The thermal properties of metal hydride were measured using the Thermal Property Analyzer based on the transient plane source (TPS) method. To verify the accuracy of the TPS method, the thermal properties of stainless steel pellets were measured prior to the metal hydride samples. Unfortunately, the thermal behavior of ...
Lime-hemp concrete (LHC) is a sustainable construction material with a low environmental impact. In this study, the thermal properties of two lime-hemp mixes with varying levels of hemp were measured to analyze the material’s ability to be used on a larger scale in cold and wet climates. A TPS Thermal Constants Analyser measured the thermal properties of the lime-hemp samples using the Transient Plane Source (TPS) method. Results showed ...
