ON PECULIAR PROPERTY OF THE VELOCITY FLUCTUATIONS IN WALL-BOUNDED FLOWS

ABSTRACT
Statistical analysis of the velocity fluctuations is performed for the near-wall region of wall-bounded flows. By demanding that the small-scale part of the fluctuations satisfies constraints imposed by local ax symmetry it was found that the small scales must be entirely suppressed in the near-wall region. This major conclusion is well supported by all available data from direct numerical simulations.
