Pore scale modeling of flows in weakly permeable porous media - a hybrid computational approach:

HGS MathComp Ladyzhenskaya Lecture

Dr. Anna Trykozko, University of Warsaw, Poland

Studying effective properties of porous media based on simulating flows at pore scale has become a widely applied procedure during last years. Realistic structures of pores are commonly obtained by X-ray computed micro-tomography (micro-CT). In this work we consider weakly permeable samples in which a significant fraction of porosity could not be detected at a micro-CT resolution. We therefore apply an approach in which parts of samples characterized as 'solids' during micro-CT imaging are treated as permeable porous media represented with an assumed (small) permeability. Reliable estimations of permeability of ‘solid’ parts were obtained by incorporating Scanning Electron Microscopy data. This way our computational hybrid approach combines two microimaging methods of different resolutions.
