Through the addition of copper oxide nanoparticles to cyclohexane in varying concentrations, a series of nano-enhanced phase change materials (NePCM) were prepared. The transient plane source (TPS) technique was used to characterize the NePCM at multiple temperatures. It was determined experimentally that increasing concentrations of nanoparticles in the liquid phase resulted in increasing thermal conductivity, but increasing nanoparticle concentration in the solid phase didn't have the same effect.Unidirectional freezing ...
The authors investigated the thermal conductivity and thermal diffusivity of two composite materials, marble and magnesium oxychloride cement. The transient plane source (TPS) technique was the method used to determine the thermal properties of the aforementioned composites. The thermal properties were studied in the temperature range from 30 to 150°C....
The transient plane source (TPS) technique was used to measure the thermal conductivity of three ceramic fibres with varying amounts of aluminium content. Specifically, the effect of temperature, press load per unit area and the aluminium content on thermal conductivity was studied. The three ceramic fibres studied were VK-60, ABK and Nextel/VK-80. It was experimentally determined that an increase in aluminium content resulted in decreased thermal conductivity of the ...
In this study, the researchers investigated the thermal conductivity, thermal diffusivity and specific heat of four types of wood: beech, birch, spruce and Douglas fir. The main factor influencing the thermal properties of the wood was the moisture content of each sample, which was manipulated by the researchers. Samples of each type of wood were taken and placed in a hot and wet air flow device for varying times in ...
A series of Er and Y sintered compounds were prepared and were subsequently tested for their thermal conductivity and electrical resistivity. The transient plane source (TPS) technique was used for the thermal conductivity measurement. These compounds were designed for use as superconductors and the authors wanted to study the electron-phonon interaction near the vicinity of Tc....
