摘要: We discuss the relevance of stochastically driven models, in particular the Euler system, in description of turbulent phenomena. We consider the statistical limit of solutions of the Navier-Stokes system modeling the fluid flow around a convex obstacle in the high Reynolds number regime. We show that the limit system cannot be statistically equivalent to the Euler system driven by temporal white noise.
