This paper discussed the creation of ceramic foams with various amounts of agar added. The foams used fly ash as the raw material in order to make them more environmentally friendly. The authors hoped that this successful use of fly ash could help to recycle that vast amounts of it that are produced each year. The effect of the various agar additions on the thermal conductivity of the foams was ...
This study outlines the design of a final repository for nuclear waste in bedrock, by the Swedish Nuclear Fuel and Waste Management Company. Thermal property testing is required to determine the canister separation distance within the repository. The transient plane source thermal constants analyzer was used to determine the thermal conductivity of anisotropic metagranite on a small-scale (centimeter), while a large-scale experiment was used for the large-scale (meter). The results ...
When testing the thermal conductivity of moist specimens, an analysis of heat and mass transfer must be conducted. Thermal conductivity measurements require a temperature gradient within the sample, however when measuring moist materials, the temperature gradient causes the moisture to be transported and dispersed within the material. During testing, phase changes can also be experienced, which may lead to latent heat. For this experiment, the thermal properties of moist autoclaved ...
Zeolites are highly insulative, porous minerals. Due to their insulating nature, heat transfer and therefore thermal conductivity is greatly impacted. With the help of a transient plane source (TPS) thermal constants analyzer, researchers tested the ability of zeolites to conduct heat when containing thermally conductive additives. This research mainly focused on metallic, ceramic and carbonaceous additives. The research conducted has shed light on the design of new porous composites experiencing ...
This study experiments with the new and improved transient plane source (TPS) method for measuring the thermal conductivity of thin-films. The existing TPS method for measuring thin-films experiences the effect of thermal contact resistance. In this experiment, a thermal constants analyzer is used to investigate the precision and efficacy of the new method. This modified method looks to resolve the issues surrounding contact resistance, with eliminating the need for reference ...
