Two-Phase Flow Clause Samples

Two-Phase Flow. Sw = [1 + (αβAA' P cAA' )n ]−m (3.6) where βAA' is the scaling coefficient for fluid pair A and A'; α and n are the adjustable parameters, and m = 1−1/n. The implementation of this model in the simulator includes scaling with intrinsic permeability (k) and porosity (φ) where α is replaced by α k . β is approximated by the ratio of water-air interfacial tension (σaw) to the interfacial tension of the fluid pair. Here and elsewhere the subscript w applies to either water or microemulsion for the case of two-phase flow with oil. βAA' = σaw / σAA'
