maybee Senior Member Join Date: Jan 2012 Posts: 166 Rep Power: 14	hi, I ve a few question about the Kolmogorow scales which are briefly described here http://en.wikipedia.org/wiki/Kolmogorov_microscales 1. length scale: - Is the length scale the size of the smallest turbulence encountered? and - Have the mesh cells to be all of the same size or even smaller in DNS (direct numerical simulation)? 2. time scale: - What is the meaning of the time scale? - What is it good for? Does it have an influence on the simulation time steps? 3.velocity-scala: - What is it good for? greetings maybee
