Abstract [en]

To predict the performance of an aquifer thermal energy system, an understanding of the system`s hydrothermal behavior is needed.^ One possibility is to run a detailed numerical simulation of the system.^ However, for a single-well system in which fluid flow is limited to steady radial flow, a characterization scheme based on a set of four dimensionless parameter groups allows production temperatures and energy recovery factors to be read from graphs.^ The assumption of radial fluid flow is valid when buoyancy flow can be neglected and a well is fully screened in a horizontal aquifer which is confined above and below by impermeable layers.^ Criteria for little buoyancy flow include a low permeability or vertically stratified aquifer, a small temperature difference between injected and ambient water, and short cycle length.^ The basic energy transport equations for the aquifer-confining layer system with steady radial fluid flow in the aquifer are nondimensionalized to derive the key parameter groups.^ Next a numerical model which calculates the heat transfer in the aquifer and confining layers for an injection-storage-production cycle is run for a range of values of these groups.The calculated production temperatures and energy recovery factors are then presented graphically as a function of the parameter groups.^ Comparisons between results of field experiments and recovery factors read from the graphs show good agreement.
