The authors state that the TPS technique isn't an accurate method for the measurement of thermal conductivity, thermal diffusivity and volumetric heat capacity of liquids. This is due to the effects of natural convection caused by the sensor which introduce a significant error in the measurements. Six commonly known liquids were investigated using the TPS technique and the obtained values were compared to literature and were found to be significantly ...
The authors used a variety of techniques to determine the thermal properties of polymethyl methacrylate (PMMA), including thermal conductivity, thermal diffusivity, specific heat and density. The measurements are performed in the temperature range from -70°C to 80°C. The results from the different techniques used to characterize the PMMA (GHP, GHF, TPS, THS) are all compared to see whether they agree with one another....
The thermal conductivity and thermal diffusivity of lithium sulphate were measured using the transient plane source (TPS) technique in the temperature range from 300 to 900 K.It was determined that thermal conductivity decreases up to 640 K, but rises past this temperature. A similar trend was observed for thermal diffusivity....
The author reports on improvements to the transient plane source (TPS) technique which deal with increasing the maximum reliability of the measurements. Optimal time of measurement, sensor temperature measurement, and uncertainty of results are explored. The theory was confirmed by experimental measurements made on polymethyl methacrylate (PMMA)....
In 1999 an earthquake ripped through Taiwan, which came to be known as the Chi-Chi earthquake. The authors of this paper drilled into the core of the fault created by the earthquake to recover samples that could be analyzed. Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of the core samples were measured. The thermal properties were measured in order to give information about frictional heat ...
