Numerical Modeling of Geothermal Use of Mine Water: Challenges and Examples

摘要: Geothermal energy, including the geothermal use of mine water, is increasingly important, due to ecological and economical reasons. Numerical flow heat transport models can help estimate efficiency such facilities. In addition, it possible test different configurations. However, modeling voids challenging because necessary simultaneously solve in surrounding porous medium within workings. Different approaches are demonstrated, as 2-D cross-sections, with 1-D elements for workings, 3-D models. It shown that numerical simulations provide sufficient validity specific goals. none currently feasible strategies be seen a perfect fully physical solution. Suggestions given on how approaches.
