Dynamical and statistical properties of large scales in turbulence
A. Alexakis, M. E. Brachet, S. Fauve +1
We present a review of results concerning the properties of scales larger than the forcing scale in turbulent flows. In three-dimensional turbulence, when the power driving the flo…
Emergent dynamical scaling in the inviscid limit of 3D stochastic Navier-Stokes equation with thermal noise
Liubov Gosteva, Marc Brachet, Léonie Canet
In this work, we investigate the Navier-Stokes equation in the presence of thermal noise, both at finite viscosity (revisiting the seminal work by Forster-Nelson-Stephen) and in th…
The Galerkin-truncated Burgers equation: Crossover from inviscid-thermalised to Kardar-Parisi-Zhang scaling
C. Cartes, E. Tirapegui, R. Pandit +1
The one-dimensional () Galerkin-truncated Burgers equation, with both dissipation and noise terms included, is studied using spectral methods. When the truncation-scale Reynold…
Geometric microcanonical theory of two-dimensional Truncated Euler flows
Adrian van Kan, Alexandros Alexakis, Marc Brachet
This paper presents a geometric microcanonical ensemble perspective on two-dimensional Truncated Euler flows, which contain a finite number of (Fourier) modes and conserve energy a…
Intermittency of three-dimensional perturbations in a point-vortex model
Adrian van Kan, Alexandros Alexakis, Marc Etienne Brachet
Three-dimensional (3D) instabilities on a (potentially turbulent) two-dimensional (2D) flow are still incompletely understood, despite recent progress. Here, based on known physica…
Quantum turbulence simulations using the Gross-Pitaevskii equation: high-performance computing and new numerical benchmarks
Michikazu Kobayashi, Philippe Parnaudeau, Francky Luddens +4
This paper is concerned with the numerical investigation of Quantum Turbulence (QT) described by the Gross-Pitaevskii (GP) equation. Numerical simulations are performed using a par…
