A dynamic network model for two-phase immiscible flow

A dynamic pore-scale network model is formulated for two-phase immiscible flow. Interfaces are tracked through the pore throats using a modified Poiseuille equation, whereas special displacement rules are used at the pore bodies. The model allows interfaces to move over several pore-lengths within a...

Zusammenfassung:A dynamic pore-scale network model is formulated for two-phase immiscible flow. Interfaces are tracked through the pore throats using a modified Poiseuille equation, whereas special displacement rules are used at the pore bodies. The model allows interfaces to move over several pore-lengths within a time step. Initial computational results are presented for a drainage experiment to demonstrate some of the features of the model.[PUBLICATION ABSTRACT]
