THERMAL MEASUREMENTS ON CONSOLIDATED AND UNCONSOLIDATED ROCKS
Research and Innovation is often related to the diffusion of new technologies. Nowadays the energy price fluctuations and the economic crisis are jeopardizing the development and diffusion of renewable energy technologies and sources. The improvement of the knowledge on thermal properties of the underground materials will help this project to achieve its challenging goals.
Therefore both standardized and new innovative methodologies are being used in order to characterize the properties of the underground.
The activity aims to provide thermal properties and their mapping methodologies. Thermal properties are detected through standardized laboratory methods, in order to update the unconsolidated and consolidated databases for the most common soils amongst the European countries which are involved in this EU project.
Currently, UNIPD and its partners are performing thermal measurements on dolomite samples, in order to check more in detail the variability of this type of rock. In order to carry out these measurements, UNIPD uses different types of instruments and devices. These measurements are going to be compared with other devices and other lab instruments at Friedrich-Alexander-Universität in Erlangen (Germany).
These pictures show several dolomite rock samples, where the thermal properties (such thermal conductivity, thermal diffusivity, heat capacity) are detected both in dry and wet conditions.
