Using the transient plane source (TPS) method, the thermal conductivities of a series of magnesium integral foams have been measured experimentally. The main factor contributing to the thermal conductivity of the magnesium foams is the bulk density. In addition to using the TPS technique, micro-computed tomography (µCT) was used to explain any deviations from expected thermal conductivity....
Through the addition of different amounts of thermally conducting B-Aluminum nitride powder to polyethylene glycol and silica gel a form-stable phase change material (PCM) is prepared. Using the Thermal Constants Analyzer, the researchers were able to measure the thermal conductivity of the PCMs. Increasing amounts of B-Aluminum nitride powder results in increasing thermal conductivity, but a decrease in the value of the latent heat. Melting temperatures were unaffected by the ...
A modification was made to the transient plane source (TPS) technique for the measurement of thermal transport properties at low temperatures (as low as 80 K). This altered TPS technique was then used to measure the properties of known samples in the form of fused silica, carbon steel and halide crystals. Data were obtained from room temperature down to 80 K. The newly modified method gave experimental results that agreed well with ...
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....
