What kind of shape has the lowest flutter wind speed and is the most unstable?
I mean for rigid body.
Yes, I know many factors affect the flutter in a MSD system (for rigid body), however I'd really want to know what is the worst case one could have? No matter what mass damper or spring one use... (I am not from the ame, Im a civil engineer)
The reason I asked this is, I want to use CFD to reproduce the phenomena, and as you may know CFD is very sensitive to the Reynolds number, so I'd like to know what is the lowest Reynolds number case that can have a clear flutter instability phenomenon.
Thanks a lot.
Sorry, my bad, forget about the questions.
