Abstract
This paper presents a numerical and experimental study to capture the free surface of a two-phase flow in a rock-flow cell. The numerical code was implemented in OpenFOAM® C++ library using the volume-of-fluid (VOF) method for moving meshes and the interface was tracked by the isoAdvector scheme. Rock-flow cell is a novel system for hydrate formation analysis, and it has been proved to capture most hydrates phenomena, however, more information of the flow is needed. Computational fluid dynamics methods can play a crucial role in given detailed information and deepen the understanding of the flow behavior in rock-flow cells, once the method is validated by experimental results. In order to ensure the reliability of present algorithm, experiments were carried out with water and air in a rock-flow cell with different rotational speeds. It was used two wire-mesh sensors in order to measure the hydrodynamic characteristics and patterns of multiphase flow. It was observed stratified and slug flow patterns. The comparison between numerical and experimental results showed a good agreement.
