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 ...
Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
In this study, the thermal properties of stainless steel, ceramic, and silica aerogels were numerically calculated and then compared to actual test results. A thermal constants analyser measured the thermal conductivities and thermal diffusivities of the samples using the transient plane source (TPS) method. Results showed that the values generated by the numerical simulation were within ±3% of the TPS method values, which verifies the reliability and accuracy of the numerical ...
