Flow, transport, and deformation in porous media are strongly interconnected through nonlinear physical, chemical, and biological processes. Depending on the research questions and applications, these processes are studied across different temporal and spatial scales, with varying structural properties and heterogeneities. These investigations show that many processes are dominated by the properties and morphology of the porous medium, as well as the dynamics of fluid-fluid and fluid-solid interfaces, which occur at significantly smaller length scales than those considered. For this reason, many existing model concepts only inadequately represent the actual system behavior. Examples of limited predictive capabilities include the extended Darcy law for multiphase flows, as well as current models for evaporation processes and crack propagation in porous media. The CRC 1313 aims to develop a fundamental understanding of how interfaces influence flow, transport, and deformation across scales in porous media. This includes both quantifying the impact of pore geometry, heterogeneity, and damage state of the porous medium on the dynamics of fluid-fluid and fluid-solid interfaces, and developing mathematical and numerical multiscale models. In the third funding phase, the subprojects focus on the Salt Vision topic in porous media. Special attention is given to salt precipitation phenomena driven by evaporation processes, as well as chemically induced calcite mineralization and dissolution. To structure the research within the CRC effectively, the research area of interface-related processes has been divided into three project areas: Project Area A deals with interface-driven exchange processes of mass, momentum, and energy for coupled free flows and flows in porous media. Project Area B addresses complex crack and failure processes in porous media. Project Area C focuses on changes in the pore space caused by processes at the fluid-solid interface. Research in all three areas combines mathematical and numerical modeling with modern multiscale, image-based experiments. All three project areas share conceptual challenges such as visualizing simulation and experimental results, defining benchmarks for model validation, and coupling multiscale simulation environments. These topics are addressed in Project Area D. Another project area supports the CRC as a central service unit with a shared experimental platform, information infrastructure, coordination of the overall project, organization of the integrated graduate school, and public relations.
