This article highlights two assumptions of TPS the technique; the probe is thermally neutral, and the heat transfer is conductive. The researchers of this article mention an uncertainty of using a technique for measuring low-density and highly insulative materials. Accordingly, numerically noised thermograms of the thermal responses were recorded and applied during measurements, and the best-fitting procedure of a technique was applied. From this, it was determined that the presence ...
This article explains the theory behind the Transient Plane Source (TPS) technique. The method measures the thermal conductivity and diffusivity of materials (solids, liquids, gels, etc.), in a rapid, non-invasive and highly accurate manner. The TPS method is a great technique to be used for thermal characterization as it has a wider thermal conductivity range (0.005 – 500 W/mK) and an easy set-up. The sensor serves as both a temperature gauge and ...
