Numerical simulation of stratified-pattern two-phase flow in gas pipelines using a two-fluid model

•A two-fluid model is discretized with the FCT method to simulate two-phase flows in gas pipelines.•Hyperbolicty is lost over a range of the Taitel and Dukler's diagram for stratified-flow pattern.•Eigenvalues alternate signs at boundaries with implications on how to impose the boundary conditi...
