... ABSTRACT A new theoretical model has been developed for determining flow regime transitions in two-phase gas-liquid flow in horizontal pipes. The theoretical model provides a physical explanation for the development of the perturbed interface of the stratified flow into a roll wave or slug...

... ABSTRACT Severe slugging is reported from some field operations, when an increase in the production rate leads to a transition from steady stratified flow to slug flow in the pipeline. The slugs can be longer than anticipated for normal hydrodynamic slugging and the flow transients can...

The flow is modelled using the volume of fluid (VOF) multiphase model, which allows for the prediction of the shape of the gas-liquid interface. Even though stratified flow is probably the simplest two-phase flow regime, only few studies of stratified...
