This mini-symposium focuses on pore-scale modeling and simulation of porous media, welcoming diverse research to advance both fundamental theory and practical applications [1], [2], [3]. Key topics include: • Novel Algorithms & Computational Methods: Development of advanced numerical approaches (LBM, PNM, finite volume/element methods, DNS, machine learning) for complex geometries, multiphase flow dynamics, and integration with experimental/digital rock data. • Model Validation: Rigorous benchmarking of computational models against lab/field data using pore-scale imaging, flow visualization, and experimental measurements. • Emerging Complexities in Porous Media Flow: Theoretical and numerical advances in multiscale flow dynamics, including multiphase flow, reactive transport, and coupled processes (e.g., chemical-pore-structure interactions). • Upscaling Pore-Scale Results: Bridging pore-scale simulations to continuum models via effective medium properties, constitutive relationships, and multiscale frameworks. • Digital Rock Physics: Advanced in digital representation of porous media structures using high-resolution imaging, segmentation, and statistical characterization of pore networks for accurate simulation inputs. • Coupled Processes with multiphase flow, reactive transport: Modeling interactions such as fluid-fluid displacement and reactive transport that alter pore structures. • CCS/CCUS Applications: Simulations of CO₂ injection, storage, and trapping mechanisms in subsurface formations. It covered the flow and transport of supercritical CO₂, mechanisms of capillary trapping, dissolution processes, reactive transport in carbonate formations, mineralizatin in basalts and saline aquifer, and assessing the long-term integrity of CO₂ storage sites The symposium aims to foster cross-disciplinary collaboration and highlight cutting-edge advances in porous media research. Submissions integrating experiments or novel computational methods are encouraged.
