Upper Bound on the Dimension of the Attractor for Nonhomogeneous Navier-Stokes Equations

Abstract

Our aim in this article is to derive an upper bound on the dimension of the attractor for Navier-Stokes equations with nonhomogeneous boundary conditions. in space dimension two, for flows in general domains with prescribed tangential velocity at the boundary, we obtain a bound on the dimension of the attractor of the form csript R signe3/2, where script R signe is the Reynolds number. This improves significantly on previous bounds which were exponential in script R signe. Keywords: Navier-Stokes equations, background flows, channel flows, Taylor-Couette flows, global attractor, functional invariant set, Hausdorff and fractal dimensions, energy dissipation rate, Reynolds number.
