Evaluation of transient measurements of thermophysical parameters using Finite Elements Method

The transient plane source (TPS) method was used to measure the thermal diffusivity and conductivity of silica glass and polymethyl methacrylate (PMMA). The results were evaluated by an analytical model and also by a numerical model created by the finite elements method (FEM). The results of both mo...

More Information
Summary:The transient plane source (TPS) method was used to measure the thermal diffusivity and conductivity of silica glass and polymethyl methacrylate (PMMA). The results were evaluated by an analytical model and also by a numerical model created by the finite elements method (FEM). The results of both models and both materials were compared, and the difference was less than 0.4%.
