Liquid toluene is a material used in industrial processes, and generally the thermal conductivity needs to be determined for efficient use. However, the thermal conductivity varies depending on high temperatures and other physical variables. The transient hot wire method has previously been used to obtain measurements of the thermal conductivity of toluene under multiple conditions to create reference data. This paper displays ...
The transient line source technique was used to take thermal conductivity measurements over the entire liquid range of toluene at 1atm. Unlike any other liquid (with the exception of water) the thermal conductivity was not completely a linear function of temperature. Instead, there was an anomaly pre-freezing where the thermal conductivity dropped from what was expected. This paper attributes this behavior to ...
This article aimed to compare the thermal conductivity of expanded glass granulate at high temperature ranges using a variety of steady state and transient testing methods (Guarded Hot Plate, Heat Flow Meter, Pipe Tester, Sphere, Hot Wire, Transient Hot Bridge). The thermal conductivity of the expanded glass granulates was determined from 170°C to 530°C with the different methods and apparatuses. The thermal conductivity was found to have increased from about 0.030 ...
This article presented the high temperature properties of high-entropy alloys (HEAs) that will potentially be used as thermoelectric (TE) generator materials. The high temperature thermal conductivity was analyzed using the transient plane source (TPS) method through the use of a Thermal Constant Analyser. From the experimental results, it was concluded that HEAs may be used as high-performance bulk TE materials at high temperatures due to their potential to reach low ...
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 ...
