Unbaffled Mixing Tank

  Hello,
  I've been looking into a mixing tank problem in which the tank is not baffled and swirlling type flow is likely. I've played around with different turbulent models in particular the RSM and LES models and have found them to work rather well. My issue is that as I look to move into multiphase flow LES seems to be uncompatable with several multiphase modules and RSM also has some drawbacks. Is there a better (more robust) option for these kind of mixing problems? Thanks

  Hello,
  
  Which multiphase model are you considering?
  "RSM also has some drawbacks" : Would you mind elaborating a bit.
  
  You may also want to explore DES turbulence model, which is compatible with Mixture and VOF multiphase model. DES resolves the large-scale turbulent motions using LES and models the smaller, unresolved turbulence using RANS.
  
  Thanks!
