This article studies the thermal properties of grout used in geothermal energy applications. A number of different cement based sealants were analyzed by the authors to understand how the thermal conductivity and thermal diffusivity change as they are exposed to conditions similar to what they withstand when they are in use. Moisture content was of particular importance, as the porous grouts easily absorb the groundwater that they come in contact ...
The goal of this masters thesis was to better understand the factors affecting the performance of geothermal heat pumps. A new method (Distributed Thermal Response Testing) of determining the ground thermal conductivity and thermal resistance around a borehole from filed data was tested. In order to test the accuracy of this method, it was compared against laboratory results and field tests. An instrument was used in a laboratory setting to ...
