Uncertainties in turbulence

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We argue that in order to reduce the inherent uncertainties caused by low-dimensional approaches (LES etc.) to treat turbulent flows at high Re, not accessible to DNS of NSE, it is necessary to study the inherent nonlocal (Tsinober, An informal conceptual introduction to turbulence, 2009 [6], Tsinober, The essence of turbulence, with emphasis on issues of paradigmatic nature, 2013 [7]) properties and relations, manifested in rich direct and bidirectional coupling of large/resolved and small/unresolved scales via non-trivial experiments at high Re. We show this by evidence from those with pointwise access to the full tensor of velocity derivatives.
