摘要: Computational pore-scale network models describe two-phase porous media flow systems by resolving individual interfaces at the pore scale, and tracking these through network. Coupled with volume averaging techniques, can reproduce relationships between measured variables like capillary pressure, saturation, relative permeability. In addition, allow nontraditional to be quantified, such as interfacial areas common line lengths. They also explorations of possible variables, well testing new theoretical conjectures. Herein we compute areas, lengths using a model. We then consider conjecture that definition an extended constitutive relationship area eliminates hysteresis drainage imbibition; is commonly seen in traditional pressure saturation. For sample under consideration, find essentially eliminated specific choice displacement rules; rules are within range experimental observations for interface displacements therefore considered physically plausible. macroscopic measures behave similarly fluid‐fluid although functional dependencies on saturation diAer some extent. ” 2001 Elsevier Science Ltd.
