I am currently considering LES for k, the resolved k to be precise. Apologies, I did not really get what you meant by "[f_fil(x,t)]_bar = F(x)" but thanks for helping me recall that in LES it is a...

Yes so I understand that both the UMean and UPrime2Mean are the population statistis that require a large T. However, I am not sure how k can be time varying when it only depends on the 3...
