✦ Synopsis
One shows that the steady-state solutions to Navier-Stokes equations in d-dimensional domains ; d = 2; 3 with Dirichlet and slip curl boundary conditions are exponentially stabilizable by proportional controllers with the support in open subsets ! ⊂ such that \ ! is su ciently "small".

Order-of-magnitude deletion of the stream-wise diffusion terms leads to a reduced form of the Navier-Stokes equations. Solving the reduced equations for internal flows with single-sweep marching algorithms requires a severe minimum stream-wise step-size to avoid unstable solutions. This behaviour is
