Seminar

Kolmogorov 4/5 law, nonlocality and sweeping decorrelation hypothesis

Tsinober, A (Imperial College London)
Wednesday 01 October 2008, 16:00-16:30

Seminar Room 1, Newton Institute

Abstract

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.
