A modified model for a borehole ground heat exchanger borefield (BHE) of a ground-source heat pump (GSHP) system was … inhomogeneous groundwater flow in the soil. The model was validated using FLUENT for a single borehole based on a constant load … along the effective length of the borehole with good agreement. The present model was then used to investigate the effect of …

of great importance for the design and sizing of borehole thermal energy systems (BTESs). In Scandinavia groundwater … groundwater flow between the borehole and the surrounding rock. An enhanced heat transport then occurs due to the induced … part of the borehole while groundwater of ambient temperature enters the borehole through fractures at larger depths. This …

In this paper different approaches to groundwater flow and its effect in the vicinity of a borehole ground heat …
