High-temperature aquifer thermal energy storage (HT-ATES) systems can help in balancing energy demand and supply for better use of infrastructures and resources. The aim of these systems is to store high amounts of heat to be reused later. HT-ATES requires addressing problems such as variations of the properties of the aquifer, thermal losses and the uplift of the surface. Coupled thermo-hydro-mechanical (THM) modelling is a good tool to analyse the viability and cost effectiveness of HT-ATES systems and to understand the interaction of processes, such as heat flux, groundwater flow and ground deformation. The main problem of this modelling is its high computational cost. We propose a dimensional and numerical analysis of the thermo-hydro-mechanical behaviour of a pilot HT-ATES. The results of this study have provided information about the dominant thermo-hydraulic fluxes, evolution of the energy efficiency of the system and the role of the hydraulic and thermal loads generated by the injection and extraction of hot water.

高温含水层蓄热的蓄热效率、地表隆起和热-水-力学现象

高温含水层热能储存 (HT-ATES) 系统有助于平衡能源需求和供应，以更好地利用基础设施和资源。这些系统的目的是储存大量热量以供以后重复使用。HT-ATES 需要解决诸如含水层性质变化、热损失和地表隆起等问题。耦合热-流体-机械 (THM) 建模是分析 HT-ATES 系统的可行性和成本效益以及了解热通量、地下水流和地面变形等过程相互作用的好工具。这种建模的主要问题是其高计算成本。我们建议对先导 HT-ATES 的热流体力学行为进行尺寸和数值分析。
