Transition from shear-dominated to Rayleigh-Taylor turbulence
Stefano Brizzolara, Jean-Paul Mollicone, Maarten van Reeuwijk +2
Turbulent mixing layers in nature are often characterized by the presence of a mean shear and an unstable buoyancy gradient between two streams of different velocity. Depending on…
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…
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…
Lagrangian coherent structures and entrainment near the turbulent/non-turbulent interface of a gravity current
M. M. Neamtu-Halic, D. Krug, G. Haller +1
In this paper, we employ Lagrangian coherent structures (LCSs) theory for the three dimensional vortex eduction and investigate the effect of large-scale vortical structures on the…
