Analysis of data on the relation between eddies and streaky structures in turbulent flows using the placebo method. (English. Russian original) Zbl 1200.76109
Fluid Dyn. 41, No. 5, 772-783 (2006); translation from Izv. Ross. Akad. Nauk, Mekh. Zhidk. Gaza 2006, No. 5, 108-121 (2006).
Summary: An artificially synthesized velocity field with known properties is used as a test data set in analyzing and interpreting the turbulent flow velocity fields. The objective nature of this approach is utilized for studying the relation between streaky and eddy structures. An analysis shows that this relation may be less significant than is customarily supposed.
