A novel concept of fractal dimension in deterministic and stochastic Lorenz-63 systems
Tommaso Alberti, Davide Faranda, Valerio Lucarini +3
Many natural systems show emergent phenomena at different scales, leading to scaling regimes with signatures of chaos at large scales and an apparently random behavior at small sca…
Chameleon attractors in a turbulent flow
Tommaso Alberti, Francois Daviaud, Reik V. Donner +3
Turbulent flows present rich dynamics originating from non-trivial energy fluxes across scales, non-stationary forcings and geometrical constraints. This complexity manifests in no…
On the investigation of properties of superfluid He turbulence using a hot-wire signal
P. Diribarne, M. Bon-Mardion, A. Girard +17
We report hot-wire measurements performed in two very different, co- and counter-rotating flows, in normal and superfluid helium at 1.6 K, 2 K, and 2.3 K. As recently reported, the…
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…
A model of interacting Navier-Stokes singularities
H. Faller, L. Fery, D. Geneste +1
We introduce a model of interacting singularities of Navier-Stokes, named pin\,cons. They follow a Hamiltonian dynamics, obtained by the condition that the velocity field around th…
A correspondence between the multifractal model of turbulence and the Navier-Stokes equations
B. Dubrulle, J. D. Gibbon
We study a correspondence between the multifractal model of turbulence and the Navier-Stokes equations in spatial dimensions by comparing their respective dissipation length sc…
