Remarks on the emergence of weak Euler solutions in the vanishing viscosity limit

We prove that if the local second-order structure function exponents in the inertial range remain positive uniformly in viscosity, then any spacetime $L^2$ weak limit of Leray–Hopf weak solutions of the Navier-Stokes equations on any bounded domain $\mathrm{\Omega }\subset {\mathbb{R}}^d$, $d=2,3$ is a weak solution of the Euler equations. This holds for both no-slip and Navier-friction conditions with viscosity-dependent slip length. The result allows for the emergence of non-unique, possibly dissipative, limiting weak solutions of the Euler equations.
