Statistical characteristics of wall turbulence

The statistical turbulence characteristics obtained by direct numerical simulation of two flows, namely, flow in a circular pipe and flow in a channel with parallel walls, are given. The velocity profiles and the distributions of the statistical moments up to the fourth order inclusive are analyzed. The calculation results are compared with known experimental and numerical data.
