Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The transient plane source (TPS) method, was used for the determination of thermal conductivity and thermal diffusivity of solid materials. Researchers developed a model based on the thermal quadrupoles formalism to represent the temperature variation. This model was able to take in account the thermal contact resistance of the material and the thermal inertia. The TPS method makes it possible to calculate the parameters estimation on all the recorded temperature ...
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 ...
