...) in various concentrations to the water/air flow. Experiments were taken both without and with foam. Various measurement techniques were used: differential pressure sensors, flow visualization, and Distributed Acoustic Sensors (DAS) (fibre optics). The focus is on (growing) slugs in the horizontal flowline...

... ABSTRACT The slug capturing technique, which is incorporated in the industrial PROMPT code is used to explore the influence of entrainment of gas bubbles at slug fronts, on slug characteristics such as slug length and frequency. The computations are compared with available field data...

... ABSTRACT Predictions from multiple industrial simulators of multiphase pipeline flow are compared to field data for a hilly terrain, gas-condensate pipeline with three-phase flow. Field conditions studied include quasi-steady flow and ramp-up slugging. Some models predict excessive terrain...

... surface, combined with the Very-Large Eddy Simulation (VLES) approach to cope with turbulence. We will first discuss new results of transition from stratified to slug flow, which agree well with the data as to water hold-up and slug frequency. We will then present new results of bubbly and slug flow...

... ABSTRACT: A Lagrangian three-phase slug tracking model is demonstrated for a severe slugging case with gas, oil and water in an S-shaped riser. The model is an extension of a hybrid twophase flow scheme in which a two-fluid model formulation is used in the stratified flow region. In the slug...
