Abstract
Prediction of coupled phenomena of heat and solute transport and water flow is important tool for dimensioning geothermal applications. We present a model and numerical simulation software, where the variable-density coupling effect is implemented to the combination of equivalent continuum and discrete fracture network (so called multidimensional model). We compare several algorithms for dealing with the non-linear terms. The importance of large-scale fractures to the qualitative and quantitative evaluation is demonstrated on model problems.
