Default Ask about the setup for Unsteady flow

Posts: n/a
Dear all,

I got a 3D airfoil model and would like to know its unsteady characteristics, however I don't have any experience in modelling unsteady flow before.

I understand I would need the strouhal number to obtain the frequency, but is there any people know~

What is the good strouhal number for airfoil?

If I assumed the strouhal number is 0.3 at the beginning and obtained a frequency, how can I check it is correct or not in FLUENT?
