DNS and LES resolution
I am a bit newbie on the LES and DNS subjects and I am wondering if someone can help me clear out a couple of question.
The kolmogorov turbulence length scale for DNS after what i have learned the the basis for grid size? Is the Taylor length scale the correct basis for LES?
To clear it out. How many cells are needed to describe the motion for the smallest turbulence length?
What is the common way to determine cell size for LES computation? I am specially interested in a wing transition problem.
