groundwater velocity with varying thermal dispersivity values, however, has a significant influence on the thermal borehole …Thermal conductivity and thermal borehole resistance are basic parameters for the technical and sustainable design of … the borehole heat exchanger (BHE) and all transport effects are combined in the parameters of effective thermal …

gradient in and around the borehole is achieved. This causes convective flow in the groundwater due to density differences. In … groundwater filled BHE the convective heat flow influences the heat transport in the borehole system. The size of the influence …During a thermal response test (TRT) or during operation of a borehole heat exchanger (BHE) system, a temperature …

In this paper an improvement of the model CaRM (CApacity Resistance Model) is presented to consider the borehole … thermal capacitance, both of the filling material of the borehole and of the heat carrier fluid inside the ground heat …-coupled heat pump systems. According to the modelling for the surrounding ground, the new approach for the inside of the borehole …
