Benchmark Solutions for the Incompressible Navier-Stokes Equations in GeneralCoordinates on Staggered Grids

摘要

Benchmark problems are solved with the stationary incompressible Navier-Stokesequations discretized with a finite volume method in general curvilinear coordinates on a staggered grid. The system of discretized equations is solved efficiently with a nonlinear multigrid algorithm, in which a robust line smoother is implemented. Furthermore, another benchmark problem is introduced and solved in which a 90 degree change in grid line direction occurs.
