The multi-component quaternary materials of the Se78-xTe20Sn2Bix (x = 0, 2, 4, 6) chalcogenide glasses system were synthesized with varying bismuth (Bi) composition by using a melt quenching technique. The thermal transport properties (effective thermal conductivity, diffusivity, and specific heat per unit volume) of the glasses were determined using the transient plane source (TPS) technique at room temperature. The TPS measurements found ...
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 study aimed to experimentally measure the thermophysical properties of cellular metals, focusing on effective thermal conductivity. The transient plane source (TPS) technique was used to measure the thermal conductivity of hollow sphere structures from different steel alloys and open cell structures made of iron-chromium-aluminum alloy (FeCrAl) for temperatures of 250°C and 800°C in air, respectively. From the experimental results, it was seen that the effective thermal conductivity values were ...
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 ...
