DNS and LES resolutionHi everyone
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. First: 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? Second: To clear it out. How many cells are needed to describe the motion for the smallest turbulence length? Third: What is the common way to determine cell size for LES computation? I am specially interested in a wing transition problem. Thanks |
