In this work, some analytical solutions of the heat conduction differential equation in two-dimensional case are presented for the geometry of the thin foil. The foil is made of a homogeneous material, and the thickness is so small that the temperature variation over it is negligible. The model is successively applied to some photothermal experimental schemes. The analysis of thermal data allows to evaluate the thermal diffusivity of the thin foil. The post-processing technique is discussed, focusing on the challenges in error analysis.

Abstract
In this work, some analytical solutions of the heat conduction differential equation in two-dimensional case are presented for the geometry of the thin foil. The foil is made of a homogeneous material, and the thickness is so small that the temperature variation over it is negligible. The model is successively applied to some photothermal experimental schemes. The analysis of thermal data allows to evaluate the thermal diffusivity of the thin foil. The post-processing technique is discussed, focusing on the challenges in error analysis.File in questo prodotto:
