Hydrate bearing sediments, found in permafrost, have great potential as a future energy source. Therefore, the thermal properties need to be determined to design drilling and gas extraction processes. The thermal conductivity was measured through a transient plane source (TPS) method. The thermal conductivity values show weak negative dependence on temperature. The effective thermal conductivity of hydrate-bearing sediment is strongly dependent on the water-saturation of the sand, the hydrates tend ...
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) method is a popular technique that is used to measure the thermal properties of solids. The TPS method is widely used because it can test a variety of materials, it is easy to set up, and measurements are non-invasive. A downside of the TPS method is that it requires two homogenous samples, unlike invasive contact-probe techniques. This study proposes the idea of a “stamp sensor”, ...
