Abstract
In this work, the dynamical behavior of an air-water slug unit cell over time was investigated. For that, three-dimensional numerical simulations were carried out in OpenFOAM. They included the Volume of Fluid (VOF) multiphase model and the κ-w Shear Stress Transport (SST) turbulence model. Slug parameters, such as the mean length, translational velocity and frequency were determined. A good correspondence between the results achieved here and those gathered from literature was found. From the 3D velocity field, wall shear stresses and momentum flux parameters were assessed. These results may be further used to improve correlations applied in one-dimensional models.
