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

Table 4

Input parameters used to generate different pore-geometries (or different -cells) and their corresponding porosity ranges. In this table, cell refers to a cell in the mesh used to discretize the -cell.

Geometry	Initial mesh dimensions	Inputs	Porosity range
In-line array of shapes (see Figure 1)	50 × 50 cells (-cell length: 1 unit)	(a) Circle diameter: 44 to 8 cells; (b) Square length: 48 to 2 cells
Staggered array of squares (see Figure 7)	100 × 50 cells (-cell length: = 0.5 units, / = 1, / = 1 as per Figure 8)	Square length: 40 to 8 cells
Randomly distributed squares (see Figure 14)	100 × 100 cells (-cell length: 1 unit)	Increasing density of squares (with constant square length: 0.01 unit = 1 cell)
