Computing and Comparing Effective Properties for Flow and Transport in Computer-Generated Porous Media
Tortuosity-porosity trends for staggered-array of squares. Simulated data is plotted against (diffusive) data from literature that employed finite difference (FD) and boundary element (BE) methods. In this geometry, hydraulic tortuosity in the direction is a weak function of porosity.
