Phase change materials have supercooling characteristics that would benefit long-term latent heat thermal energy storage. This paper studied the physical and chemical properties associated with the growth rate of crystallization in disodium hydrogenphosphate dodecahydrate (DHD) as a function of a degree of supercooling. The transient plane source (TPS) technique was used to measure the thermal conductivity of the DHD samples. Results of the thermal conductivity test showed that the solid ...
In this study, a modification to the transient hot-strip (THS) method demonstrated that the thermal properties of two different materials can be measured simultaneously when placed on either side of the hot-strip sensor. Three experiments tested samples of gabbro with a regular THS sensor, a wood sensor, and a fused quartz sensor, respectively. The accuracy of the results was better than 3% between each measurement. Despite a large difference in the ...
