Different porous materials exhibit widely varying pore structures, from foams and
fibrous materials that have wide-open, highly
interconnected pore spaces to geologic materials with
limited connectivity and strong spatial correlations in
pore structure. These differences in pore scale structure
can have a strong effect on transport properties,
especially multi-phase behavior,
dispersion, particle transport, and fluid displacements.
Modern network models are often mapped directly from real materials. Because these
network models are described using rigorous geometric
parameters, they provide an excellent tool for pore-space
characterization in addition to flow modeling.
Quantitative parameters that can be extracted directly
from the network data files include pore-size
distributions, throat size distributions, pore
interconnectivities, pore and throat surface areas, pore
aspect ratios, throat cross sectional areas, and more.
