Analytical Solution for the Simulation of Ground Thermal Conditions Around Planar Trench Collectors
Authors: Adinda Van de Ven, Peter Bayer, Roland Koenigsdorff
Published In: Geothermics, Volume 124 (2024)
This paper presents a novel analytical model for simulating ground thermal conditions around vertically installed planar trench collectors, a promising alternative for geothermal heat supply in areas with depth or space restrictions. The research introduces a three-dimensional analytical approach that models heat conduction and seasonal temperature variations in the ground. Validated through numerical simulations and experimental data, the model provides an efficient and accurate tool for designing trench collectors, emphasizing their application in geothermal systems.
Key contributions include:
- A new framework for rapid and reliable dimensioning of trench collectors.
- Validation with field data from an experimental site in Germany.
- Insights into improving geothermal system efficiency and adaptability.
