Computing and Comparing Effective Properties for Flow and Transport in Computer-Generated Porous Media

Figure 10

Anisotropic ratios in staggered-array of squares. For all porosities, the anisotropic ratios for hydraulic and diffusive tortuosity are less than one, indicating that the hydraulic flow and passive diffusive transport are more tortuous in the direction than in the direction. The hydraulic flow is more permeable in the direction.
