Thermo-physical properties of multi-component Se_78-xTe₂₀Sn₂Pb_x chalcogenide glasses

The Transient Plane Source (TPS) technique was used to evaluate the thermal transport characteristics (such as thermal conductivity, thermal diffusivity, specific heat per unit volume) in multi-component Se_78-xTe₂₀Sn₂Pb_x glasses at room temperature. From the experimental results, it was noted that thermal conductivity decreased with lead (Pb) content in the ternary Se₇₈Te₂₀Sn<...

Microencapsulation of phase change materials with binary cores and calcium carbonate shell for thermal energy storage

This article aimed to analyze the abilities of self-assembled microcapsules containing calcium carbonate shells and paraffin-based binary cores to act as thermal energy storages. The thermal properties of the microcapsules, such as thermal conductivity and phase change properties, were obtained using the transient plane source (TPS) method and analyzed using an instrument. It was found that the thermal conductivity of the microcapsules was enhanced due to their highly thermally conductive ...

Nitrogen doped hybrid carbon based composite dispersed nanofluids as working fluid for low-temperature direct absorption solar collectors

This article studied the thermal conductivity of deionized (DI) water and ethylene glycol (EG) based nanofluids with varying temperatures for different volume fractions of N-(rGO-MWNTs) (nitrogen doped hybrid structure of reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWNTs)). The thermal conductivity was found by using the transient plane source (TPS) method by using a Thermal Analyser. From the experimental results, it was noted that the thermal conductivity of ...

Thermal properties and thermal structure in the deep-water coalbed basin off the Shimokita Peninsula, Japan

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....

Thermal and physical properties of reconsolidated crushed rock salt as a function of porosity and temperature

Crushed salt can be used as a backfill in salt repositories to bury and conduct heat away from radioactive waste in salt repositories. Since crushed salt compacts during reconsolidation, its thermo-physical properties will vary because of changes in porosity. A Transient Plane Source thermal constant analyzer was used to measure thermal conductivity of the salt samples. Thermal conductivity was found to decrease with increasing temperatures....
