Modeling insulated borehole heat exchangers

Environmental Earth Sciences, 2016
In the heating sector, borehole heat exchangers have become popular for supplying renewable energy. They tap into the subsurface to extract geothermal energy for heating purposes. For advanced applications, borehole heat exchangers require insulation in the upper part of the borehole either to meet legal requirements or to improve their performance.

Borehole thermal resistance of U-tube borehole heat exchanger

Géotechnique Letters, 2016
Thermal resistance of U-tube borehole heat exchangers (UBHE) is one of the factors that controls their design. Several equations are available in the literature to estimate the thermal resistance of UBHE. However, these equations produce different results and no definitive recommendation is available regarding their validity.

Theoretical Model of Borehole Heat Exchanger

Journal of Energy Resources Technology, 2004
The paper deals with the possible use of existing oil wells for geothermal energy production. A mathematical model, describing the process of exploitation of a borehole heat exchanger, has been worked out. It was used for determining energy efficiency, employing the main parameter, i.e., flow of produced heat energy.

Borehole heat exchanger with nanofluids as heat carrier

Geothermics, 2018
Abstract This paper presents numerical study on the use of nanofluids to replace conventional ethylene glycol/water mixture as heat carrier in a BoreHole Heat Exchanger. Nanofluids contain suspended metallic nanoparticles: increasing their concentration, in comparison to the base fluid, the thermal conductivity increases and the volumetric heat ...
