May 1, 2017, 00:53	Eulerian bubbly flow simulation with periodic boundary conditions	#1
Shehryar New Member Ali Shehryar Join Date: Dec 2016 Posts: 13 Rep Power: 10	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 Last edited by Shehryar; May 1, 2017 at 00:54. Reason: typo
