Hello.

I believe there is such a correlation. As far as I know, it is called Lighthill's analogy. Howevere, if you are working with an internal flow with boundaries the integral scale of turbulence may be very important, too. Some time before I've developed a code for industry which deals with acoustics of ducted propellers (reported at ECMI conference). Can send you a copy of the report. Perhaps, it maight be of use for you.

Yours sincerely.

Gregory Vilensky.
