In deep sedimentary basins, geothermal processes are significantly affected by heat transport properties. In this study, thermal properties of deep sediment core samples were measured using a thermal constant analyzer with transient plane source method. Results showed that thermal conductivity of the sediment near the seafloor was low and increased with depth. Thermal conductivity of coal was lowest of all samples, while cemented rock exhibited the highest thermal conductivity....
In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se85-xTe15Sbx (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of ...
The objective of this study was to evaluate the transient plane source method for thermal conductivity and diffusivity of food and agricultural materials. An instrument was used to measure thermal conductivity of liquid and solid samples. Thermal conductivity and diffusivity values determined by the TPS method were in close agreement with reported literature values....
In this study, the influence of silver phase on thermal properties of BaTiO₃/Ag composites are investigated. A thermal analyzer was used to measure the thermal conductivity and thermal diffusivity of the composites at ambient and elevated temperature up to 175°C. Results found that for a fixed silver composition, the thermal conductivity of the composite remained nearly constant below its tetragonal to cubic transformation temperature (120°C), then decreased and stayed ...
The phase behavior of polymeric materials is understood through glass transition temperature. It is a temperature boundary above which the polymeric material is soft and viscous, and becomes hard, brittle, and glassy below this temperature. In the present work, PS/PMMA immiscible polymer blend samples are studied at different compositional ranges. Thermal transport properties of PS/PMMA polymeric blends were measured , from room temperature to 120°C. Variation in thermal conductivity ...
