Numerical investigations on gas-liquid distribution characteristics of intermittent flows in a pipeline-riser system

In this work, VOF model has been introduced to simulate gas-liquid two phase intermittent flow phenomena in a pipeline-riser system. During the flow processing, air and water has been set as the fluid medium, and various operation conditions have been tested in details. As been shown in results, there are mainly air bubbles and slugs in the riser section under different operation conditions. In addition, various fluid medium has been tested for comparison, which will have a positive impact on further research.
