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....) |
