Final Report Abstract

Coping with non-linearities and the question of upscaling are outstanding challenges in environmental, technical, and biological applications within the field of flow and transport in porous media. A variety of characteristic (spatial and temporal) scales can be identified in porous media, generally related to the structure of their heterogeneities. The flow and transport phenomena in these media can be caused by coupled mechanisms resulting from the non-linear interplay of physical, chemical, and/or biological processes. To tackle the problems in this field, an interdisciplinary approach is crucial. The participating scientists excel in such diverse fields as applied mathematics, scientific computing, physics, environmental and civil engineering, geosciences, and petroleum engineering. Fundamental research (e.g. the development of stochastic methods and basic theories of flow and transport in porous media) and research on the optimisation of efficient numerical schemes were interlinked with applied research in various fields (e.g. the optimisation of fuel cells or the geological sequestration of carbon dioxide). One central aspect of the International Research Training Group on Non-linearities and Upscaling in PoroUS Media (NUPUS) was the study programme, which aimed at fostering a coherent combination of education of and research by young scientists. This was achieved by organising advanced courses which met the needs of the young scientists involved, implementing a local, biweekly ’graduate school seminar’ for discussing research results, and an exchange programme allowing the doctoral students to spend six to nine months in one of the partner countries. The biweekly seminar was made available to students and supervisors from the other universities via videoconferencing. The resulting international and interdisciplinary environment enabled the qualifying fellows as well as the doctoral and postdoctoral researchers to perform highly efficient work at a top level of scientific research in non-linearities and upscaling in porous media systems. With the help of the the International Research Training Group NUPUS, porous-media research and education has gained a high strategic and structural importance for the University of Stuttgart.
