KurzbeschreibungThis course presents advanced topics of single/multiphase fluid flow, heat transfer, reactive transport, and geochemical reactions in the subsurface. Emphasis is on the understanding of the underlying governing equations of each physical and chemical process, and their relevance to applications, e.g., groundwater management, geothermal energy, CO2 storage, waste disposal, and oil/gas production.
LernzielThis course presents the tools for understanding and modeling basic physical and chemical processes in the subsurface. In particular, it will focus on fluid flow, reactive transport, heat transfer, and fluid-rock interactions in a porous and/or fractured medium. The students will learn the underlying governing equations, followed by a demonstration of corresponding analytical or/and numerical solutions.
By the end of the course, the student should be able to:
1. Understand, formulate, and derive the governing equations of fluid flow, heat transfer, and solute transport;
2. Understand and apply the underlying physical and chemical processes to simplify and model practical subsurface problems;
3. Solve simple flow problems affected by fluid density (induced by the solute concentration or temperature);
4. Understand and be able to assess the uncertainties pertaining to the reactive transport processes;
5. Assess simple coupled reactive transport problems.
