Dear Comsol community,
I'm trying to model a flow of water in air. The flow is created by a moving wall (like in a syringe). The wall is moving at a speed of 1 mm/s. All the dimensions on the GIF file linked to this topic are in mm.
I've coupled the "Two-Phase Laminar Flow, Phase Field" and "Moving Mesh" physics. I use the Phase Field method rather than the Level Set one since it's faster to compute results with it, and because the Phase Field physics can be coupled with the Solid Mechanics one (future work).
I keep obtaining results like in the GIF file. It creates peaks on the surface of the liquid while it should be horizontal, and the flow isn't going down like expected.
Has someone already experienced these kinds of results and could help me resolving them please ? That would be a great help !!
Best Regards,
Robin
