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 …

Onsager's 'ideal turbulence'theory

The inviscid limit for the Navier–Stokes equations with data analytic only near the boundary

I Kukavica, V Vicol, F Wang - Archive for Rational Mechanics and Analysis, 2020‏ - Springer
We address the inviscid limit for the Navier–Stokes equations in a half space, with initial
datum that is analytic only close to the boundary of the domain, and that has Sobolev …

An Onsager singularity theorem for Leray solutions of incompressible Navier–Stokes

TD Drivas, GL Eyink - Nonlinearity, 2019‏ - iopscience.iop.org
We study in the inviscid limit the global energy dissipation of Leray solutions of
incompressible Navier–Stokes on the torus, assuming that the solutions have norms for …

Josephson-Anderson relation and the classical D'Alembert paradox

GL Eyink - Physical Review X, 2021‏ - APS
Generalizing the prior work of PW Anderson and ER Huggins, we show that a “detailed
Josephson-Anderson relation” holds for drag on a finite body held at rest in a classical …

On the energy and helicity conservation of the incompressible Euler equations

Y Wang, W Wei, G Wu, Y Ye - Journal of Nonlinear Science, 2024‏ - Springer
In this paper, we are concerned with the minimal regularity of weak solutions implying the
law of balance for both energy and helicity in the incompressible Euler equations. In the …
