Fluid-Structure Interaction with Two Fluid Phases
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two-Phase Flow, Phase Field application mode in the MEMS Module.The model geometry consists of a small container, in the middle of which is an obstacle. Initially a heavier fluid (water) is present in the left domain and air is present everywhere else. A feedback loop allows the displaced air to move from the right domain back to the left domain.
