			Abstract

The stationary Navier-Stokes equations are solved in 2D with
preconditioned GMRES. The preconditioning matrix is derived from a
semi-implicit Runge-Kutta scheme. The spectrum of
the preconditioned coefficient matrix indicates that
this approach will be successful. Numerical experiments for the flow over a
semi-infinite flat plate show that the preconditioning makes GMRES
converge substantially faster especially for high Reynolds
numbers. The number of iterations proves to be independent of the
Reynolds number.
