Finding a reconnection in a vortex-haystack
Abhishek Harikrishnan, Benjamin Musci, Adrien Lopez +8
Counter-rotating vortex reconnection is a topology-transforming event that leads to strong vorticity amplification and is often associated with the most irregular regions of the ve…
The Excess Dissipation of Energy in a Turbulent Boundary-Layer and its Departure from Log-Normality
Benjamin Musci, Sebastien Aumaitre, Enzo Francisco +2
We investigate turbulent dissipation in a von Karman flow using PIV and Diffusing Wave Spectroscopy measurements to directly compare bulk and wall dynamics. While bulk dissipation…
Experimental measurement of the vorticity-strain alignment around extreme energy transfer events
Benjamin Musci, Berengere Dubrulle, Jean LeBris +5
This work experimentally explores the alignment of the vorticity vector and the strain-rate tensor eigenvectors at locations of extreme upscale and downscale energy transfer. We sh…
Spontaneous stochasticity in a 3d Weierstrass-ABC flow
Antoine Barlet, Adam Cheminet, Bérengère Dubrulle +1
Chaotic systems are characterised by exponential separation between close-by trajectories, which in particular leads to deterministic unpredictability over an infinite time-window.…
On Lagrangian Intermittency from 4-D Particle Tracking Velocimetry measurements of a turbulent von Kármán flow
Valentina Valori, Paul Debue, Adam Cheminet +9
We investigate the ability of 4D Particle Tracking Velocimetry measurements at high particle density to explore intermittency and irreversibility in a turbulent swirling flow at va…
Double frame Tomographic PTV at high seeding densities
Philippe Cornic, Benjamin Leclaire, Frédéric Champagnat +4
A novel method performing 3D PTV from double frame multi-camera images is introduced. Particle velocities are estimated by following three steps. Firstly, separate particle reconst…
