Dense flow with DEM+CFD

albatroz · January 19, 2015, 19:36

Hello everybody,

I'm simulating dense multiphase flow with CFD+DEM. I found this on some papers, but none of them tells the software used.

I'm trying with the Star-CCM + 9.02.005, but have tried everything to couple the Lagrangian phase (DEM) with the Eulerian phase (Continuum).

My case: the gas-solid slug flow occurs in a horizontal pipe, i.e., there is dense and dilute phases simultaneously. I tried something about Passive Scalar Model, but there is limited informations about it. Another approach was inserted vacuum in downstream pipe, but without success.

My problem is: how to drag the particles coupling the Lagrangian and Eulerian phases?

If anyone can help me, thank you very much.

Is possible couple Lagrangian with Eulerian phase without special field functions? I need help, so much. Thanks.

I am also having issues with creating a fluid which interacts with DEM particles, can anyone provide me with information, a tutorial or a file which simulates this?
