We consider the problem of the strong convergence, as the viscosity goes tozero, of the solutions to the three-dimensional evolutionary Navier-Stokesequations under a Navier slip-type boundary condition to the solution of theEuler equations under the zero flux boundary condition. In spite of thearbitrarily strong convergence results proved in the flat boundary case, see[4], it was shown in reference [5] that the result is false in general, byconstructing an explicit family of smooth initial data in the sphere, for whichthe result fails. Our aim here is to present a more general, simpler andincisive proof. In particular, counterexamples can be displayed in arbitrary,smooth, domains. As in [5], the proof is reduced to the lack of a suitablepersistence property for the Euler equations. This negative result is proved bya completely different approach.
