[OpenFOAM] Slug Flow

Multiphase flow of oil and gas in pipelines is a common and challenging phenomenon in the energy industry, as it can exhibit different flow regimes such as stratified, annular, and slug flow. Accurate prediction of these behaviors is essential for ensuring safe operation, reducing pressure fluctuations, and optimizing production.

In this project, the interFoam solver in OpenFOAM was used to simulate oil–gas flow. The solver applies the Volume of Fluid (VOF) method to capture the interface between phases, enabling the study of flow regime development and interface dynamics.
