Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
This article describes the design, theory, advantages, and limitations of the TPS technique with a modified bridge. It also describes testing that has been done using the technique on a variety of solid materials from temperatures of 77 K to 1000 K. It was found that at any temperature, the testing was highly accurate, with a deviation of less than 2% when compared to recommended values....
The authors make some kind of modification to the TPS technique and then call it the advantageous TPS (ATPS) technique, which apparently has an improved experimental arrangement. It is also claimed that there is more automation in data acquisition, better accuracy and easier calculations. Fused quartz, low carbon steel and silver chloride crystals are studied with the ATPS technique, with the use of liquid nitrogen to cool the silver chloride ...
A modification was made to the transient plane source (TPS) technique for the measurement of thermal transport properties at low temperatures (as low as 80 K). This altered TPS technique was then used to measure the properties of known samples in the form of fused silica, carbon steel and halide crystals. Data were obtained from room temperature down to 80 K. The newly modified method gave experimental results that agreed well with ...
