Abstract
Pore-scale network models provide insights into two-fluid porous-media flow systems. Their ability to simulate laboratory experiments allows continuum-scale constitutive relationships to be derived from these models. Because all fluid-fluid interfaces are modeled explicitly, quantities that are difficult or impossible to measure, such as interfacial areas, can be calculated within the model. This allows new constitutive relationships to be investigated, and theoretical conjectures to be tested. In one such test, a functional dependence between interfacial area, capillary pressure, and saturation is observed, but the extended interfacial area function still exhibits hysteretic behavior. Additional calculations involving contact-line length, mass-transfer phenomena, and dynamics of interface motion allow additional relationships to be developed and tested.
