Dear rfblumen,

Thanks for your reply, it was really complete. I have a few answers/questions/doubts:

  • Unluckily, the recirculation affects the entire vaneless diffuser, therefore moving the interface can't really help.
  • About the Frozen Rotor, should the pitch be the same between vaned diffuser and impeller?
  • For sure the TBR method is the best for this kind of problem. I was trying to avoid it because of the computational cost, but if it's unavoidable I will go for it.

Thanks once again for your help
