Z02: Porous Media Lab (PML) - A platform for image-based in-situ experiments for porous media

Project Z02 (Porous Media Lab) provides experimental infrastructure and expertise for studying flow, transport, and deformation in porous media. It supports CRC 1313 with microfluidics and in-situ XRCT, enabling high-resolution, real-time imaging. Key advances include custom micromodels, novel imaging setups, and 4D data tools. Research addressed fracture mechanics, salt precipitation, and carbonate dissolution. Upcoming goals focus on dynamic fatigue tests, spectral XRCT, and tracer-based microfluidic analysis. The lab drives benchmarking and validation efforts across the CRC. Strong collaborations amplify its scientific and technical impact.
