Abstract: Interface Tracking Techniques (ITM) are used for stratified slug-flow in pipes. ITM is combined with the Very-Large Eddy Simulation (V-LES) approach to cope with turbulence. We first present 2D validation results, and then discuss new results of transition from stratified to slug flow. We will then present results of droplet entrainment in a stratified flow with lower water cut. While turbulence has long been addressed using RANS, we show that new approaches are mature enough to be employed as viable alternatives to statistical approaches, including the filter-based approach, also known as V-LES, which constitutes a blend between URANS and LES.
