Sergei B. Kuksin On distribution of energy and vorticity for solutions of 2D Navier-Stokes equation with small viscosity (331K, pdf) ABSTRACT. We study distributions of some functionals of space-periodic solutions for the randomly perturbed 2D~Navier-Stokes equation, and of their limits when the viscosity goes to zero. The results obtained give explicit information on distribution of the velocity field of space-periodic turbulent 2D~flows.
