Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
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 are nano-porous materials with impressive thermal insulation properties. This study uses a new theoretical model to predict the effective thermal conductivity of aerogels based on gas and solid conduction, as well as thermal radiation. A thermal constant analyzer measured the influence of gas pressure, atmosphere, and temperature on the thermal conductivity of nano-porous materials using the transient plane source (TPS) method. Results showed that the experimental thermal conductivity values ...
