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

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 …

[HTML][HTML] Vapor bubble nucleation in flowing liquids
In this work, a stochastic diffuse interface model coupled with the Navier–Stokes equations
has been exploited to numerically investigate vapor nucleation in a non-equilibrium system …
