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…
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…
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…

Validation of a model for estimating the strength of the vortex created by a Vortex Generator from its Bound Circulation
Martin O. L. Hansen, Antonios Charalampous, Jean-Marc Foucaut +2
A hypothesis is tested and validated for predicting the vortex strength induced by a vortex generator in wall-bounded flow by combining the knowledge of the Vortex Generator (VG) g…
Comparison of turbulence profiles in high Reynolds number turbulent boundary layers and validation of a predictive model
Jean-Philippe Laval, John Christos Vassilicos, Jean-Marc Foucaut +1
The modified Townsend-Perry attached eddy model of Vassilicos et al (2015) combines the outer peak/plateau behaviour of rms streamwise turbulence velocity profiles and the Townsend…
Attached flow structure and streamwise energy spectra in a turbulent boundary layer
Sricharan Srinath, J. C Vassilicos, Christophe Cuvier +3
On the basis of (i) Particle Image Velocimetry data of a Turbulent Boundary Layer with large field of view and good spatial resolution and (ii) a mathematical relation between the…
New criteria to detect singularities in experimental incompressible flows
Denis Kuzzay, Ewe-Wei Saw, Fabio J. W. A. Martins +4
We introduce two new singularity detection criteria based on the work of Duchon-Robert (DR) [J. Duchon and R. Robert, Nonlinearity, 13, 249 (2000)], and Eyink [G.L. Eyink, Phys. Re…
