twoPhaseEulerFoam for flow inside a cyclonic separator
 
Hi All,

I'm wondering if anyone has tried to simulate a flow inside a cyclonic separation using twoPhaseEulerFoam, example air + sand. I'm trying to simulate this problem base on ~/tutorial/multiphase/twoPhaseEulerFoam/bed solver, but the simulation become unstable after a few seconds.

When I tried with one phase only (air) using pisoFoam, the simulation is OK without any problems, and I can see the swirling flow inside the cyclone. I suspect that, with the particle, the centrifugal force make the particle to move very fast and then somehow :confused:... make the simulation unstable (I might be wrong on this). Does anyone have any different idea why I cannot simulate this cyclone geometry?

I'm happy to send the mesh or other files from the three principle folders (~/0 ~/system ~/constant ) if anyone interested.

Cheers :)

HI Mali,

I am iterested in this topic. I would like to do the separator analysis. Do you already have a working case ? Or could you send me the mesh and settings ?

Thanks

Peter

Please send it to me @dutta_ruma@yahoo.com

Please send me the mesh file too.

I heard that, cyclone mesh is quite unstable...I might cause the problem. Anyway, I am working on this twophaseeulerFoam now, and i'm willing to discuss with you guys.

Have you found out what was wrong with your settings? Please send me your files, I can try to figure out something. lukasz0004@gmail.com

Thanks you in advance.
