Well my opinion is that method is not useful at all, I may be wrong though. With your boundary conditions your approach will be very cumbersome because you need to compute Fourier coefficients using...

I'm not an expert in openFoam and I rather develop my own codes. I would say that I disagree with that equation because the subgrid scale dresses are a...

I was about to ask you, how are you sure that you are solving 95% of the scales in the domain ( isotrooic zoned) and 10% close the walls without a plot of the spectrum of the kinetic energy? At least...

You must check the spectrum to make sure your grid cut-off lies on the inertial subrange from the energy spectrum. However, your doubt can be very specific to your model....
