Thermal properties of asphalt concrete: A numerical and experimental study

Asphalt concrete must often endure a range of different weather conditions, and its thermal conductivity is affected by these changes. Using the Finite Element Method (FEM), this paper develops a two-dimensional numerical model used to study and predict environmental effects and validates it through experimental results from the transient plane source method. It was also shown that an increase in the ratio of the TPS sensor size to the maximum ...

Using transient plane source sensor for determination of thermal properties of vacuum insulation panels

Researchers at the Chalmers University of Technology used the transient plane source (TPS) method to propose a technique for testing layered materials of a low conductive core, coated in a highly conductive thin film. The accuracy of the method to evaluate isotropic materials was tested prior to testing the ability of the TPS to analyze layered materials. Value differences were noted between the simulated and the measured temperature increases of ...
