Fiber Tracking Velocimetry for two-point statistics of turbulence
Stefano Brizzolara, Marco Edoardo Rosti, Stefano Olivieri +3
We propose and validate a novel experimental technique to measure two-point statistics of turbulent flows. It consists in spreading rigid fibers in the flow and tracking their posi…
Role of vortical structures for enstrophy and scalar transport in flows with and without stable stratification
M. M. Neamtu-Halic, J. -P. Mollicone, M. van Reeuwijk +1
In this paper, we investigate the enstrophy dynamics in relation to objective Eulerian coherent structures (OECSs) and their impact on the enstrophy and scalar transport near the t…
Efficient mate finding in planktonic copepods swimming in turbulence
François-Gaël Michalec, Itzhak Fouxon, Sami Souissi +1
Zooplankton live in dynamic environments where turbulence may challenge their limited swimming abilities. How this interferes with fundamental behavioral processes remains elusive.…
Objective barriers to the transport of dynamically active vector fields
George Haller, Stergios Katsanoulis, Markus Holzner +2
We derive a theory for material surfaces that maximally inhibit the diffusive transport of a dynamically active vector field, such as the linear momentum, the angular momentum or t…
Connecting the time evolution of the turbulence interface to coherent structures
M. M. Neamtu-Halic, D. Krug, J. P. Mollicone +3
The surface area of turbulent/non-turbulent interfaces (TNTIs) is continuously produced and destroyed via stretching and curvature/propagation effects. Here, the mechanisms respons…
