Abstract: The Hot Disk Transient Plane Source thermal constants analyzer stands out in the field of thermal conductivity testing equipment due to its ability to measure anisotropic materials. In this paper, the mathematical derivation of the equation used in the anisotropic software module of the Hot Disk TPS is used to calculate the thermal conductivity and thermal diffusivity of three Italian tree species; larch, oak, and spruce. Axial thermal conductivity was found to be much higher than radial thermal conductivity.
