Two way FSI and flutter of fan blade

Nevel · October 6, 2009, 05:33

Hi all!
Have anybody used 2way FSI to catch flutter mode? I mean self-excited oscillation of fan blade.
Is it possible?
I simulate some blade but has damping of vibration in all cases.
Maybe some recommendations? Tips and tricks?
Thanks a lot!

FSI should be able to do this. I don't know if FSI can work in a rotating frame of reference. You will need to check that. But FSI certainly can do flutter on fixed wings, eg aircraft wings.
