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 transient plane source (TPS) technique has a wide range of applications because of its capability to test solids, liquids, powders, and anisotropic materials over a range of sizes. Thermal properties of thin films and coatings can also be characterized using the TPS method if the samples are placed between the sensor and a bulk background. To minimize errors with the TPS method, use identical materials on each side of ...
Gas hydrates have potential to be used as future energy sources, so it is important to understand their thermal properties. This paper aims to examine the effective thermal conductivity of synthetic porous methane hydrate samples. A Thermal Constants Analyser measured the thermal conductivity of the methane hydrate samples using the single-sided transient plane source (TPS) method. Results showed an inverse relationship between porosity and thermal conductivity. Unfortunately, mechanical pressure can ...
