Technologies for mesuring thermal diffusivity, thermal conductivity, and thermal expansion – 1 ECTS

Detail:The aim of the lesson is to provide the principles of operation and the description of some techniques used to determine the thermal conductivity, thermal diffusivity, and thermal expansion of thermal energy storage materials. This first version presents the theoretic background, the experimental procedures, and some apparatuses that can be applied for obtaining the thermal conductivity and diffusivity. In particular, the following techniques are considered: the Transient Plane Source (TPS) Method, a miniaturized Poensgen type apparatus, and a home-made technique based on the use of heat flux meters (sensors).
