Knowing the thermophysical properties of insulating building materials is essential in understanding heat loss. In this study, the thermal conductivity and thermal diffusivity of five marble samples were measured using the transient plane source (TPS) technique and compared to results obtained through the transient hot strip (THS) method. The TPS technique is nearly twenty times the initial resistance of the THS method and does not require small sample sizes or ...
This article describes comprehensive testing performed to increase understanding of how the thermal conductivity of ceramic fibers is affected. Non fibrous material content, temperature, and pressure were the main parameters investigated. Three different ceramic fiber samples were used in the research. Researchers discovered that the incorporation of aluminum reduced the thermal conductivity and consequently improved the insulation performance of the sample. An increase in pressure increased the thermal conductivity of ...
The thermal properties of five sandstones were measured. The sandstones were taken from the base of Khewra located in Pakistan. The thermal conductivity, thermal diffusivity, and specific heat capacity were determined using the transient plane source technique, and the porosity and density of the sandstone samples were also determined. A formula for the estimation of thermal conductivity was modified to better fit the experimental data, and it was determined that ...
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....
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 ...
