A model is presented for heat rejection in the subsurface. Geometries of different dimension are coupled by linear and general extrusions. In that way it is possible to deal with multi-scale physical set-up. An example shows the high influence of groundwater flow.

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by a finite-element simulation method, developed through the software package COMSOL Multiphysics 3.4.
