An Analysis Of Temperature Plume Distance For Bhe With Groundwater Advection

In the ground source heat pump (GSHP) system, the temperature around the borehole exchangers (BHEs) would continue to spread further because of the heat accumulation, in addition the groundwater advection would have an important impact on the thermal dispersion. In order to have more accurate spacing between holes for design, the definition of temperature plume distance is proposed, based on the steady-state model with groundwater advection in porous media, the approximate analytical expression of temperature plume distance was obtained, the factors affecting the temperature plume distance was analyzed by comparing to infinite line source (ILS) model.
