Description: Das Projekt "Teilprojekt A3: Mehrphasenprozesse in porösen Medien" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Institut für Wasserbau durchgeführt. Computer simulations of processes in the subsurface are based upon mathematical models for multiphase flow in porous media. They treat the concurrent movement of more than one fluid phase in a solid skeleton (e.g. flow of water, oil, air in soil) and are subject to permanent further development (e.g. Helmig R., 1997 (1)). In many cases, these fluids are miscible and the models therefore also have to consider the multiple components within the phases. Often, phase change by evaporation/condensation takes place which is additionally coupled with an exchange of energy. The special relevance of these complex simulations lies in the fact that, in different fields of technical applications, they are the only practible forecasting instrument because the high costs or the long-term time frame of experiments make the latter infeasible. Current challenges in environmental engineering comprise problems like, for instance, the long-term storage of the greenhouse gas CO2 by injection into the subsurface to stop global warming or the remediation of contaminated sites. To tackle these problems, today's engineers need reliable, fast and robust simulation algorithms. The current work uses the program system MUFTE-UG (developed in cooperation with the former SFB 404 project C4) as its basis (Helmig R. et al., 1998 (2)). It is designed as a research code to combine the modelling of the relevant physical processes with the application of new discretisation techniques and solution methods including, for example, multigrid and parallelisation strategies.
