Résumé

Geothermal energy is an abundantly available renewable energy source that has not yet been exploited to its full potential citing issues related to longevity of geothermal wells. Precipitation of salts within the wells pose a major threat to premature closure of many geothermal wells. A priory knowledge regarding the potential minerals that may precipitate within the well may result in finding solutions to avoid scaling beforehand. In this regard, porousMedia4Foam is used to investigate hydro-geochemistry within a geothermal well. For the solution that is injected through the feedzone, we noticed that the system is oversaturated with respect to some minerals, which indicate potential scaling within the well. We further analyse highresolution (Navier-Stokes-based) simulations for the well where we realise potential mixing zones caused due to the vortices that developed at the corners of the expanding cross-sections of the well.
