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 ...
Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of concrete and wood samples were measured at elevated temperatures. The measured values are compared to established literature values and show good agreement....
Surfactants are often used in nanofluids to help improve dispersion and prevent aggregation of the resident nanoparticles. In this study, the researchers used the transient plane source (TPS) technique to measure the thermal conductivity of a variety of nanofluids with different surfactants of varying concentrations, at different temperatures and pH values. For surfactants, thermal conductivity stabilizes after the addition of a certain concentration of that surfactant. Strongly acidic and alkaline ...
Thermal conductivity and thermal diffusivity were simultaneously measured using the transient plane source (TPS) technique. These values were measured during heating from 303 to 323 K and cooling from 323 to 303 K. It was determined that both thermal conductivity and diffusivity were at their maximum at 313 K, which is in the range of the glass transition temperature....
The ceramic Cecorite 130P was analyzed using the transient plane source (TPS) technique in order to measure the thermal conductivity in the range from 88 to 280 K. Fused quartz samples were also investigated in order to ensure the technique worked at liquid nitrogen temperatures. The thermal conductivity of Cecorite 130P was determined to have a slight dependence on temperature, with a maximum around 170 K....
