The ceramic Cecorite 130P was analyzed using the transient plane source (TPS) technique in order to measure the thermal conductivity in the range from 88 to 280 K. Fused quartz samples were also investigated in order to ensure the technique worked at liquid nitrogen temperatures. The thermal conductivity of Cecorite 130P was determined to have a slight dependence on temperature, with a maximum around 170 K....
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....
Using the TPS method, the authors measured the thermal conductivity and thermal diffusivity of samples of Swedish wood. They also looked at the effect of density, porosity and anisotropy on the measured thermal properties. Both longitudinal and transverse measurements were taken at temperatures ranging from 20°C to 100°C and an increase in temperature resulted in a slight increase in thermal conductivity. The types of mechanisms that lead to heat conduction ...
