Enhanced Multipole Method For The Thermal Analysis of Vertical Geothermal Boreholes

Thermal inertia of the grout and of the ground located close to the borehole play an important role in the thermal response of geothermal boreholes to rapidly varying heating and cooling needs in buildings. The classical multipole method, developed by Bennet, Claesson, and Hellström, does not consider that thermal inertia reason why the enhanced multipole method was recently proposed by the author. The present work gives a brief overview of the enhanced multipole method to facilitate its implementation by third parties.
