Geothermal exchangers are exploited as tools for the indirect analysis of the thermal properties of the underground material. Two simple inverse problems based on different heat transfer models are proposed: the cylindrical model of heat transfer yielding the thermal parameters of the borehole, and a forced convective model producing the soil thermal profile. We test our approach on a synthetic dataset and a real experiment.

Abstract
Geothermal exchangers are exploited as tools for the indirect analysis of the thermal properties of the underground material. Two simple inverse problems based on different heat transfer models are proposed: the cylindrical model of heat transfer yielding the thermal parameters of the borehole, and a forced convective model producing the soil thermal profile. We test our approach on a synthetic dataset and a real experiment.File in questo prodotto:
