This article discusses the theory and details the experimental procedures for measuring the thermal conductivity, thermal diffusivity, and specific heat capacity using the transient plane source (TPS) and the dynamic plane source (DPS). Parameter estimation theory enabled the analysis of sensitivity coefficients to define the optimal time window for testing. Experimental measurements were performed on polymethylmetacrylate (PMMA) and polycarbonate....
Using the dynamic plane source (DPS) technique, the thermal properties of highly and lowly thermally conducting materials were measured. The theory behind the technique is explained, and three well known materials are analyzed and the accuracy of the method is found to be within 5% of the actual value....
The authors describe the dynamic plane source, a transient method of measuring the thermal conductivity, diffusivity and specific heat of a sample. This method uses a sensor, and relies on the premise of an adiabatic system. Using this method, the thermal properties of cast iron, pure iron and stainless steel are measured. The experimentally obtained values match with the literature values quite closely....
