Experimental Validation of a Numerical Model - Application of an Open Source Algorithm towards Geothermal Conditions

Numerical modeling of at least real conditions needs to be confronted to experiments. Regarding some questioning of the geothermal energy use, in this study, a numerical model is built up. This structure and the development of the modular model are presented. It can calculate the chemical water-rock interaction within the flow and is set up in an open source environment using PhreeqC for the chemistry and Elmer for the transport (3D). The coupling of these ones, being sequential, allows to modeling the time evolution of hydraulic and transport properties induced by the chemical environment evolution. So far, for the validation of the numerical model a 1D and 2D case are considered.
