✦ Synopsis

An embedding approach, based on Fourier expansions and boundary integral equations, is applied to the vorticity-stream function formulation of the Navier-Stokes equations. The algorithm only requires efficient solvers of scalar elliptic equations and, in an asymptotic version, the boundary element method is only needed to solve the Laplace equation. The capabilities of this embedding method, in both its full and asymptotic versions, are pointed out by considering the classical problem of the flow between two eccentric cylinders.

We show that for the P N -P N -2 spectral element method, in which velocity and pressure are approximated by polynomials of order N and N -2, respectively, numerical instabilities can occur in the spatially discretized Navier-Stokes equations. Both a staggered and nonstaggered arrangement of the N -
