Abstract

An analysis of the effects that groundwater flow has on the thermal regime created by a ground source energy system is presented. The change in the development of the sub-surface thermal regime caused by a groundwater flow across a site, relative to a scenario where groundwater flow does not exist, is examined. Analysis is performed using bespoke finite-element formulations of both single- and multi-borehole systems. The results of this work show that even a modest groundwater flow across a site can lead to a significant change in the development of the sub-surface thermal regime.
