Through the addition of expanded graphite (EG) to polyethylene glycol, the authors were able to enhance the thermal conductivity of the phase change material (PCM). The transient plane source (TPS) technique was used to measure the thermal conductivity of the PCM. The amount of EG affected thermal conductivity, while amount of polyethylene glycol affected latent heat. Through the use of EG, the thermal conductivity was raised fourfold.....
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 authors prepare two series of wood sand concretes by using two types of sand concretes (dune and river) and variable amounts of wood shavings in the mixture. The mechanical and thermal properties of the concretes were then studied, using the transient plane source (TPS) technique. The addition of wood shavings to the sand concrete mix improved the strength of the concretes, and didn't have much of an effect on ...
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....
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 ...
