Abstract
We prove that if the local second-order structure function exponents in the inertial range remain positive uniformly in viscosity, then any spacetime weak limit of Leray--Hopf weak solutions of the Navier-Stokes equations on any bounded domain , 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.
