Abstract: The Hot Disk method, most commonly known as 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 Hot Disk temperature variation. This model was able to take in account the thermal contact resistance of the material and the thermal inertia. The Hot Disk TPS method makes it possible to calculate the parameters estimation on all the recorded temperature measurements. This method is also used to estimate the uncertainty due to approximations in the heat transfer model.
