Thermal conductivity of 47 pairs of granitic rock specimens were measured using the Transient Plane Source (TPS) method. Crystalline rocks are being considered for the construction high-level radioactive waste (HLW) disposal systems. Dry and wet samples, the effect of water saturation, and the influence of temperature were all factors investigated in this study....
This conference paper describes extensive investigations performed on sediment cores containing methane hydrates recovered from beneath the sea floor. Great care was taken to perform thermal conductivity measurements at similar temperature and pressure to the natural conditions that these hydrates develop and are deposited in. Measurements were taken with the samples under both water saturated and gas saturated conditions. Thermal conductivity values obtained from both conditions at temperatures over the ...
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 ...
