Fluctuation relations at large scales in three-dimensional hydrodynamic turbulence

A Alexakis, S Chibbaro, G Michel - Europhysics Letters, 2023 - iopscience.iop.org
It has long been conjectured that, in three-dimensional turbulence, velocity modes at scales
larger than the forcing scale follow equilibrium dynamics. Recent numerical and …

Statistical equilibrium of large scales in three-dimensional hydrodynamic turbulence

JB Gorce, E Falcon - Physical Review Letters, 2022 - APS
We investigate experimentally three-dimensional (3D) hydrodynamic turbulence at scales
larger than the forcing scale. We manage to perform a scale separation between the forcing …

Statistical properties of two-dimensional elastic turbulence

H Garg, E Calzavarini, S Berti - Physical Review E, 2021 - APS
We numerically investigate the spatial and temporal statistical properties of a dilute polymer
solution in the elastic turbulence regime, ie, in the chaotic flow state occurring at vanishing …

Nonuniversal velocity probability densities in two-dimensional turbulence: The effect of large-scale dissipation

YK Tsang - Physics of Fluids, 2010 - pubs.aip.org
We show that some statistical properties of forced two-dimensional turbulence have an
important sensitivity to the form of large-scale dissipation, which is required to damp the …

Temporal large-scale intermittency and its impact on the statistics of turbulence

L Bentkamp, M Wilczek - arXiv preprint arXiv:2312.08281, 2023 - arxiv.org
Turbulent flows in three dimensions are characterized by the transport of energy from large
to small scales through the energy cascade. Since the small scales are the result of the …

Exact third-order structure functions for two-dimensional turbulence

JH Xie, O Bühler - Journal of Fluid Mechanics, 2018 - cambridge.org
We derive and investigate exact expressions for third-order structure functions in stationary
isotropic two-dimensional turbulence, assuming a statistical balance between random …

[HTML][HTML] Lagrangian statistics in weakly forced two-dimensional turbulence

MK Rivera, RE Ecke - Chaos: An Interdisciplinary Journal of Nonlinear …, 2016 - pubs.aip.org
Measurements of Lagrangian single-point and multiple-point statistics in a quasi-two-
dimensional stratified layer system are reported. The system consists of a layer of salt water …

Statistical conservation law in two-and three-dimensional turbulent flows

A Frishman, G Boffetta, F De Lillo, A Liberzon - Physical Review E, 2015 - APS
Particles in turbulence live complicated lives. It is nonetheless sometimes possible to find
order in this complexity. It was proposed in Falkovich et al.[Phys. Rev. Lett. 110, 214502 …
