Prof. Dr. Rainer Helmig - Computational Methods for Multiphase Flow in Porous Media
University of Stuttgart
Phenomena of multiphase flow and transport in porous media are the subjects of active research in many disciplines.
Classically, during the past decades, civil and environmental engineering as well as the geosciences have been dealing with the treatment and management of contaminated aquifer systems, (atomic) waste disposal sites, moisture transport in concrete and soils and with the stability analysis of geotechnical systems. Petroleum engineers have been examining the flow of oil, water, and gas in reservoirs. In recent years, new issues related to flow and transport in porous media have arisen. Among them are, in the environmental field, the sequestration of CO2 in the subsurface and the hydraulic and mechanical interactions of fluid flow and the porous medium itself. In the field of computation and simulation for industrial and technical applications, the very latest scientific topics include research on flow and transport processes in paper manufacturing, the optimization of fuel cells or filter systems. Also, in biomechanics, flow and transport processes in the human liver during carcinoma therapies have gained increasing attention. The lecture is focused on a consistent and easily accessible formulation of the fundamental phenomena and concepts of a uniform description of mathematical and numerical modeling, and the latest developments in the field of simulating multiphase processes in porous media.
The emphasis is not only on discussing general aspects of the selection of relevant processes and corresponding parameters, but also the mathematical and numerical modeling concepts.
