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.…
