An investigation was undertaken to try to gain insight into altered thermal properties of the seafloor near Japan caused by the earthquake and subsequent tsunami that devastated Japan and caused the meltdown of the nuclear reactor in Fukushima in 2011. Core samples of rock were drilled by the JFAST project and these samples were analyzed using the transient plane source (TPS) technique to determine thermal conductivity, thermal diffusivity and volumetric heat ...
The authors state that the TPS technique isn't an accurate method for the measurement of thermal conductivity, thermal diffusivity and volumetric heat capacity of liquids. This is due to the effects of natural convection caused by the sensor which introduce a significant error in the measurements. Six commonly known liquids were investigated using the TPS technique and the obtained values were compared to literature and were found to be significantly ...
The authors created a series of composite latent storage materials (CLSM) using expanded graphite (EG) and a two different metal nitrate phase change materials (K and Li, K and Na). The steady-state comparative method was used in order to measure thermal conductivities because it was deemed the best technique. Properties investigated that were related to the effective thermal conductivity were material temperature and microstructure and their effect on thermal conductivity....
