3d Steady Compressible Navier–stokes Equations

On Stationary Solutions for 2 - D Viscous Compressible Isothermal Navier-Stokes Equations

We consider the Navier–Stokes equations for compressible isothermal flow in the steady two dimensional case and show the existence of a weak solution in the case of periodic and of mixed boundary conditions.

Existence of Global Weak Solutions for 3d Degenerate Compressible Navier-stokes Equations

In this paper, we prove the existence of global weak solutions for 3D compressible Navier-Stokes equations with degenerate viscosity. The method is based on the Bresch and Desjardins entropy conservation [2]. The main contribution of this paper is to derive the Mellet-Vasseur type inequality [32] for the weak solutions, even if it is not verified by the first level of approximation. This provid...

A Parallel Compressible 3D Navier-Stokes Solver Using Unstructured Meshes

We describe in this paper a strategy for parallelising a 3D compressible Navier-Stokes solver using unstructured meshes on a class of message-passing MIMD machines. The performance results obtained on two parallel machines, the Meiko Concerto and Intel iPSC860 are presented and compared to those obtained on CRAY.

EulFS : A Parallel CFD Code for the Simulation of Euler and Navier-Stokes Problems on Unstructured Grids

We present results with a parallel CFD code that computes steady-state solutions of the Reynolds-Favre averaged Navier-Stokes equations for the simulation of the turbulent motion of compressible and incompressible Newtonian fluids. We report on preliminary experiments on 2D and 3D problems, for both internal and external flow configurations. In this communication we present numerical results wi...
