ON THE MODELLING OF SLUG FLOW

Abstract

Abstract A novel approach to modelling transient slug flow is presented. Aspects of current physical descriptions of slug flow, required as closure laws for the models are briefly reviewed. It is demonstrated how the dynamics of large scale changes in slug flow may be simulated, by incorporating a unit cell type of slug flow model into numerical transient two-fluid models.
