Hello Experts, Hope you are all fine.
I am trying to simulate periodic flow of an Air-Water bubbly system using Eulerian model, transient. the mesh is attached. mesh.PNG
i am using zero pressure gradient and enabled gravity to introduce the buoyancy effect. but when i run the simulation, after about 25 seconds, these ( results.PNG ) strange vertical lines start appearing.
Plus, what should be the operating density for my simulation? i have used water density as the operating density but it underpredicts the slip velocity. Kindly guide me about this too.
Thank you in anticipation
