pressure fluctuations
 

Hallo

does there exist any procedure or equation which enables to calculate pressure fluctuations in turbulent flow.

I need some simple formula which can fastly predict pressure fluctuations in flow. Only for estimation purpose!

thanks

hm, I doubt there's something reliable, otherwise, why would people bother doing LES?

Maybe this bit helps:
The freestream turbulent intensity is often said to be 5-10% of the mean free stream velocity, so you would end up roughly with the same fluctuations in pressure (or, using Bernoulli's law for incom. along a streamline, sth in that range....)
