Peculiar Strouhal Number in FLUENT
 

Dear all,

I am currently analysing the noise generated by a rod-airfoil configuration in ansys fluent. For the geometry and domain I used the dimensions given in a paper.
When I use FFT to plot Strouhal number against PSD I get St numbers in a range from 0-10,000. I do not understand what I did wrong, so it would be great if someone could help me out.

Thank you very much in advance.
