The Transient Plane Source was used to measure the thermal conductivity of three commonly used building materials in Libya. Changes in construction practices have resulted in houses being constructed of much thinner materials in comparison to the traditionally thick walls common a few decades ago. Technical data that would make modelling heat flow is these newly constructed buildings is lacking. The indoor environment of these newer buildings often undergoes large ...
This article discusses the theory and details the experimental procedures for measuring the thermal conductivity, thermal diffusivity, and specific heat capacity using the transient plane source (TPS) and the dynamic plane source (DPS). Parameter estimation theory enabled the analysis of sensitivity coefficients to define the optimal time window for testing. Experimental measurements were performed on polymethylmetacrylate (PMMA) and polycarbonate....
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....
A YBa2Cu3O7-delta superconductor was prepared, as well as a version doped with cobalt. These materials were then analyzed using the transient plane source (TPS) technique to determine thermal conductivity. Doping with cobalt resulted in a lower thermal conductivity by a factor of 2....
A series of Er and Y sintered compounds were prepared and were subsequently tested for their thermal conductivity and electrical resistivity. The transient plane source (TPS) technique was used for the thermal conductivity measurement. These compounds were designed for use as superconductors and the authors wanted to study the electron-phonon interaction near the vicinity of Tc....
