Recently, the research group led by Zhang Dan from the School of Earth Sciences and Engineering at Nanjing University has made progress in the quantitative estimation of groundwater flow based on the thermal response of energy piles. By analysing the full-cycle thermal behaviour of energy piles during heating, cooling, and recovery stages, the team developed a full-cycle energy pile–groundwater (FC-EPG) thermal response model and a segmented multi-stage inversion framework, enabling accurate and stable estimation of groundwater flow rates under different operational modes. The research results were published in Energy under the title “Estimation of Groundwater Flow Rates based on the Thermal-Hydro Response of Energy Pile: A Multi-Stage Inversion Framework with Optimisation Algorithm.” (https://www.sciencedirect.com/science/article/pii/S0360544225051709)
