✦ Synopsis
We analyze a finite-element approximation of the stationary incompressible Navier-Stokes equations in primitive variables. This approximation is based on the nonconforming P I/Po element pair of Crouzeix/Raviart and a special upwind discretization of the convective term. An optimal error estimate in a discrete HI-norm for the velocity and in the L'-norm for the pressure is proved. Some numerical results are presented.

A new finite difference method for the discretization of the incompressible Navier -Stokes equations is presented. The scheme is constructed on a staggered-mesh grid system. The convection terms are discretized with a fifth-order-accurate upwind compact difference approximation, the viscous terms ar
## Abstract This paper discusses approximation schemes for adjoints in control of the instationary Navier–Stokes system. It tackles the storage problem arising in the numerical calculation of the appearing adjoint equations by proposing a low‐storage approach which utilizes optimal checkpointing. F
## Abstract We give here an error estimate for a finite volume discretization of the Stokes equations in two space dimensions on equilateral triangular meshes. This work was initiated by an analogous result presented by Alami‐Idrissi and Atounti for general triangular meshes. However, in this latte
