The thermal properties of oil palm shell (OPS) are investigated to determine if it could be used as a lightweight aggregate for a concrete mixture. The thermal conductivity, diffusivity, and specific heat were all tested through a transient plane source (TPS) method. The thermal conductivity and diffusivity both increased as the volume fraction of OPS increased. This is because OPS is very porous which gives it an inherently low thermal ...
This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using a transient plane source (TPS) method. As the R:W increases so does the thermal conductivity, this is because there is more conductive solids present to transfer more energy....
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 ...
