Information

Model for the heat transfer between the fluid and within the borehole filling for a single borehole segment. This model computes the dynamic response of the fluid in the tubes, the heat transfer between the fluid and the borehole filling, and the heat storage within the fluid and the borehole filling.

This model computes the different thermal resistances present in a single-U-tube borehole using the method of Bauer et al. (2011) and computing explicitely the fluid-to-ground thermal resistance Rb and the grout-to-grout resistance Ra as defined by Claesson and Hellstrom (2011) using the multipole method.
