Cascades and transitions in turbulent flows

A Alexakis, L Biferale - Physics Reports, 2018 - Elsevier
Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

Mathematical and physical ideas for climate science

V Lucarini, R Blender, C Herbert… - Reviews of …, 2014 - Wiley Online Library
The climate is a forced and dissipative nonlinear system featuring nontrivial dynamics on a

Dissipation-range fluid turbulence and thermal noise

D Bandak, N Goldenfeld, AA Mailybaev, G Eyink - Physical Review E, 2022 - APS
We revisit the issue of whether thermal fluctuations are relevant for incompressible fluid
turbulence and estimate the scale at which they become important. As anticipated by …

On the violation of the zeroth law of turbulence in space plasmas

R Meyrand, J Squire, AA Schekochihin… - Journal of Plasma …, 2021 - cambridge.org
The zeroth law of turbulence states that, for fixed energy input into large-scale motions, the
statistical steady state of a turbulent system is independent of microphysical dissipation …

Numerical dissipation vs. subgrid-scale modelling for large eddy simulation

T Dairay, E Lamballais, S Laizet… - Journal of Computational …, 2017 - Elsevier
This study presents an alternative way to perform large eddy simulation based on a targeted
numerical dissipation introduced by the discretization of the viscous term. It is shown that this …

Hyperviscosity, Galerkin truncation, and bottlenecks in turbulence
