Through the use of computed tomography and the TPS method, the authors of this article were able to calculate local effective thermal conductivities of aluminium foams synthesized through the powder metallurgical route. Computed tomography was first used in order to measure the density of a given area of the sample and this density was then used in the TPS measurements in order to generate local effective thermal conductivity values....
The authors present a method for measuring the thermal conductivity and thermal capacity of thin insulating and super-insulating materials. The new method is compared to previously existing methods and elaborates upon why these methods are unacceptable for the measurement of thin insulating materials. The researchers developed a 3D and 1D model in order to aid in the determination of thermal conductivity. The proposed method involved sandwiching a sensor/heater between ...
Expanded graphite (EG)/paraffin composite materials were prepared with the weight % of EG varying from 0 to 10%. It was found that the addition of EG to paraffin greatly improved the thermal conductivity of the material. The melting and freezing points of the PCM were compared to those of the pure paraffin. Also the heat storage/retrieval rates were studied and demonstrated improved properties....
The researchers proposed a method used to measure the thermal conductivity and heat capacity of low thermal conductivity materials with accuracy better than 10%. DSC was also used to determine thermal contact between the sample and the DSC furnace....
Using the TPS method, the thermal conductivities of a variety of metallic hollow sphere structures (MHSS) were measured. The thermal conductivities were also calculated using Misnar's analytical model and compared to the experimental results, with good agreement between the two sets of data....
