High temperatures play a crucial role in the deterioration of the thermal properties of rocks and can threaten the structural integrity of many applications in engineering. This research focused on the variations in thermal diffusivity of sandstone after high temperature heating. Thermal properties of the samples were measured before and after heating using a thermal constants analyzer based on the Transient Plane Source (TPS) technique. Thermal diffusivity of the sandstone ...
This study looked to analyze temperature effects on thermal transport properties of dry granite, gabbro, marble, and sandstone samples. An instrument was used with a high temperature chamber to perform thermal conductivity measurements on the rock samples. The thermal conductivity of the granite, marble, and sandstone samples were found to decrease with increasing ambient temperature, while the gabbro remained almost constant....
This article examined the effective thermal conductivity (ETC) of reactive packed beds made of hydriding materials. In order to properly design a packed bed of hydriding material, it is vital to know its heat transfer characteristics. The transient temperature profile measurement was performed using the transient plane source (TPS) method and the thermal conductivity values of non-reactive (oxidized) and activated Ti1.1CrMn under various hydrogen pressures were determined. The ETC ...
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 Se78-xTe20Sn2Pbx glasses at room temperature. From the experimental results, it was noted that thermal conductivity decreased with lead (Pb) content in the ternary Se78Te20Sn<...
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 ...
