Abstract
The results of an experimental verification of the theory of locally homogeneous turbulence in a mixing layer, a boundary layer, two-dimensional and axisymmetric wakes and, moreover, in the three-dimensional wake of a cylinder of finite length are presented. Since the characteristic dimensions of most of the flows investigated were very large (integral scales of turbulence of up to 1 m), at very large Reynolds numbers high resolution was achieved. The measurements showed that the quantities C and ν characterizing the inertial interval of the turbulence spectrum are not universal constants, as previously assumed, and in the flows in question, irrespective of their type, are uniquely determined by the intermittency factor.
