- Abstract
- Geothermal energy is gaining wide attention as highly efficient renewable energy and being increasingly used for heating/cooling system of buildings. The standing column well(SCW) is especially efficient, cost-effective, and suitable for Korean geological and hydrological condition. The model performs the hydro-thermal coupled analyses and simulates heat transfer through advection, convection, and conduction. And the density variation of groundwater is considered using Boussiensq approximation in modelling. The accuracy of the model was verified through comparisons with field data measured at SCWs in Korea. Comparisons indicated that the SCW numerical model can closely predict the performance of a SCW.
