讲座题目：Modelling the performance of deep borehole heat exchanger and large-scale ground source heat pump system based on the dual-continuum finite element approach in OpenGeoSys
In recent years, due to the high efficiency and environmental friendliness, medium and deep geothermal resources are increasingly being applied for building heating purposes in northern China. In the long-term, the efficiency and sustainability of deep borehole heat exchangers (DBHE) are always the focus of the industry. The thermal extraction rate, as well as the spacing between BHEs, are key parameters during the designing of such system. Supported by the NNSFC project Nr. 41628203, Junior Professor Shao and his team developed a numerical model based on the dual-continuum finite element approach. His presentation will introduce the basic mathematical principles of the newly developed code. Several modelling scenarios was constructed, representing the long-term operation of DBHEs and BHE arrays. Results will be presented with analysis on the heat extraction performance of such systems.
Dr. Haibing Shao is currently a working group leader at the Helmholtz Centre for Environmental Research (UFZ, German National Laboratory) and serves as the Junior Professor of Geothermal Systems Analysis at the Freiberg University of Mining and Technology. His research focuses on the application of numerical modelling techniques for the analysis and optimization of geothermal systems. In recent years, his research direction is focusing on the sustainability and efficiency analysis of borehole heat exchangers in ground-source heat pump systems under long-term operation. Since 2019, Junior Professor Shao started to act as the Editor-in-Chief for the international academic journal Geothermal Energy (Web of Science listed, IF=1.732).
