✦ Synopsis

The relation between the lattice Boltzmann method, which has recently become popular, and the kinetic schemes, which are routinely used in computational fluid dynamics, is explored. A new discrete velocity method for the numerical solution of Navier-Stokes equations for incompressible fluid flow is presented by combining both the approaches. The new scheme can be interpreted as a pseudo-compressibility method and, for a particular choice of parameters, this interpretation carries over to the lattice Boltzmann method.

## Abstract We examine the convergence characteristics of iterative methods based on a new preconditioning operator for solving the linear systems arising from discretization and linearization of the steady‐state Navier–Stokes equations. For steady‐state problems, we show that the preconditioned pr

We develop and analyze a least-squares finite element method for the steady state, incompressible Navier-Stokes equations, written as a first-order system involving vorticity as new dependent variable. In contrast to standard L 2 least-squares methods for this system, our approach utilizes discrete
