Hello there

I'm student and I working on research project. I have done some simulation on a planes plates with Re_tau=395.
I have found some DNS values of reynolds stress by MOSER KIM and MANSOUR but I have a problem with those values.
They give me the dissipation, production, P-strain and diffusions terms but not the Reynold stress term directly.
I know that

DRij/Dt=Production + Diffusion + P-strain - Dissipation.

But I want the Rij term and I don't know how to calculate it because of the D/Dt.

Maybe you can help me. I'm stuck in my research because of that

on the utexas site they have everything, including the re stresses.


there is also very accurate data from vreman+kuerten for re+=590 and 180 somewhere on the net.

You are looking in the wrong folder. You have to look at the .reystress file in the profiles folder
