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....
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 ...
A series of chalcogenide glasses were prepared by substituting In into Se80Te20 to replace Te. The transient plane source (TPS) technique was then used to measure the thermal conductivity, thermal diffusivity and specific heat of the glass samples. It was determined that the substitution of Te with In caused the thermal conductivity of the sample to increase, although specific heat values remained nearly constant. Specific heat was also determined ...
Using the dynamic plane source (DPS) technique, the thermal properties of highly and lowly thermally conducting materials were measured. The theory behind the technique is explained, and three well known materials are analyzed and the accuracy of the method is found to be within 5% of the actual value....
The authors describe the dynamic plane source, a transient method of measuring the thermal conductivity, diffusivity and specific heat of a sample. This method uses a sensor, and relies on the premise of an adiabatic system. Using this method, the thermal properties of cast iron, pure iron and stainless steel are measured. The experimentally obtained values match with the literature values quite closely....
