The Nature of High Reynolds Number Turbulence

Results of experiments at high Reynolds numbers – both field an airborne – are used to validate an equivalent form of the 4/5 Kolmogorov, which demonstrate one of important aspects of non-locality of turbulent flows in the inertial range and stand in contradiction with the sweeping decorrelation hypothesis understood as statistical independence between large and small scales. This is supported by a set of exact purely kinematic relations also validated experimentally.
