Pore scale modelling of porous media — •Andreas Lemmer and Rudolf Hilfer — Institut für Computerphysik, Universität Stuttgart,70569 Stuttgart, Deutschland

Flow and transport through geological, biological and industrial porous media typically involve multiple length and/or time scales. However, experimental approaches for structural analysis like micro-computertomography are limited in problem size or resolution. Based on a continuum model for porous media^[1], we discretize three-dimensional laboratory sized images of porous stones at multiple resolutions^[2]. Calculating and analyzing resolution dependent geometric and transport parameters allows quantitative validation of different theoretical approaches and comparison with experiment.
