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 ...
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 ...
In this study, the effective thermal conductivity of compacted granular beds is investigated. Thermal conductivity was measured using the transient plane source technique. Granular beds of varying particle sizes were analyzed using various sensor sizes. Results found the effective thermal conductivity to increase with increasing granule size. Smaller sensor sizes were also found to give a larger effective thermal conductivity....
In this study, effective thermal conductivity of nanocomposites containing thermally conductive aluminum nitride (AIN) nanoparticles reinforced with high-density polyethylene (HDPE) was investigated. Measurements were performed using a Thermal Constant Analyzer. The authors found that effective thermal conductivity of HDPE/AIN composites with 20 vol.% of AIN nanoparticles shows an enhancement by about 40%, compared to pure HDPE at 30°C....
