Currently, there is no research into the accuracy of the transient plane source (TPS) method for measuring the thermal conductivity of thin films. The purpose of this study is to use numerical simulation to determine the accuracy of thermal conductivity measurements of thin films, with the TPS method. The values produced from the TPS method closely resembled those of the numerical simulation. The deviations from the numerical model were caused ...
High intensity focused ultrasound (HIFU) is a new noninvasive method for treating certain tumors. Tissue mimicking phantoms are used to test HIFUs because it provides real time visualization of HIFU induced lesion evolution, and can calibrate the HIFU transducers. This study investigates the thermophsyical properties of egg white phantoms at room temperature, and varying concentrations of egg white. Measurements of thermal conductivity, diffusivity, and specific heat were taken using a ...
The high temperature fire resistance of vanadium is not well documented, so its properties are usually approximated to the same as conventional structural steels. The goal of this study is to determine the properties that influence the fire resistance of structural steel, thermal conductivity, specific heat and thermal elongation. Thermal conductivity and specific heat were both determined through a transient plane source (TPS) method. Vanadium and A36 steel were both ...
This study analyses a mullite ceramic formed through foaming and starch consolidation of mullite powder, and how its thermal conductivity changes with porosity of the ceramic. The thermal conductivity was measured through the transient plane source (TPS) method with the TPS. As the porosity of the mullite ceramic increases so does the thermal conductivity....
Hydrate bearing sediments, found in permafrost, have great potential as a future energy source. Therefore, the thermal properties need to be determined to design drilling and gas extraction processes. The thermal conductivity was measured through a transient plane source (TPS) method. The thermal conductivity values show weak negative dependence on temperature. The effective thermal conductivity of hydrate-bearing sediment is strongly dependent on the water-saturation of the sand, the hydrates tend ...
