Spontaneous stochasticity amplifies even thermal noise to the largest scales of turbulence in a few eddy turnover times

D Bandak, AA Mailybaev, GL Eyink, N Goldenfeld - Physical review letters, 2024 - APS
How predictable are turbulent flows? Here, we use theoretical estimates and shell model
simulations to argue that Eulerian spontaneous stochasticity, a manifestation of the …

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 …

Onsager's 'ideal turbulence'theory

G Eyink - Journal of Fluid Mechanics, 2024 - cambridge.org
In 1945–1949, Lars Onsager made an exact analysis of the high-Reynolds-number limit for
individual turbulent flow realisations modelled by incompressible Navier–Stokes equations …

Fluctuating hydrodynamics and the Rayleigh–Plateau instability

B Barker, JB Bell, AL Garcia - Proceedings of the National Academy of …, 2023 - pnas.org
The Rayleigh–Plateau instability occurs when surface tension makes a fluid column become
unstable to small perturbations. At nanometer scales, thermal fluctuations are comparable to …

Fluctuating hydrodynamics and Debye-Hückel-Onsager theory for electrolytes

A Donev, AL Garcia, JP Péraud, AJ Nonaka… - Current Opinion in …, 2019 - Elsevier
We apply fluctuating hydrodynamics to strong electrolyte mixtures to compute the
concentration corrections for chemical potential, diffusivity, and conductivity. We show these …

Non-local fluctuation phenomena in liquids

F Croccolo, JM Ortiz de Zárate, JV Sengers - The European Physical …, 2016 - Springer
Fluids in non-equilibrium steady states exhibit long-range fluctuations which extend over the
entire system. They can be described by non-equilibrium thermodynamics and fluctuating …

Heterogeneous bubble nucleation dynamics

M Gallo, F Magaletti, CM Casciola - Journal of Fluid Mechanics, 2021 - cambridge.org
Heterogeneous nucleation is the most effective mechanism for the inception of phase
transformation. Solid walls and impurities act as a catalyst for the formation of a new …

Clebsch gauge fluid

S Yang, S **ong, Y Zhang, F Feng, J Liu… - ACM Transactions on …, 2021 - dl.acm.org
We propose a novel gauge fluid solver based on Clebsch wave functions to solve

Large-scale influence of numerical noises as artificial stochastic disturbances on a sustained turbulence

S Qin, S Liao - Journal of Fluid Mechanics, 2022 - cambridge.org
We investigate the large-scale influence of numerical noises as tiny artificial stochastic
disturbances on a sustained turbulence. Using two-dimensional (2-D) turbulent Rayleigh …
