    Abstract

    A parallel high-order accurate solver for the incompressible Navier-Stokes equations is described in this paper. The spatial discretization of the Navier-Stokes equations, the compact low-pass filter that is used to enhance numerical stability and the implementation are discussed in detail. Particular emphasis is on the treatment of stencils of various finite-difference and filter expressions in the vicinity of sub-domain interfaces, which result from the decomposition of the computational domain for parallel computations. Results for a time-dependent flow consisting of a vortex pair developing a long-wavelength instability are presented. The resolving properties and the numerical efficiency of the method are discussed.
