Abstract
At high Reynolds numbers, it is very difficult to solve the Navier-Stokes equations because of its numerical instability. This difficulty is due to the very small viscous diffusion. The eddy viscosity moEnl introduces a rather large diffusion into the system, which stabilizes the computation. It is natural to ask whether the high-Reynoldsnumber flow fields can be obtained without introducing a turbulence moEnl or sub-grid moEnling.
