BENCHMARK SOLUTIONS FOR THE INCOMPRESSIBLE NAVIER-STOKES EQUATIONS INGENERAL COORDINATES ON STAGGERED GRIDS

Benchmark problems are solved with the steady incompressible Navier-St okes equations discretized with a finite volume method in general curv ilinear co-ordinates on a staggered grid. The problems solved are skew ed driven cavity problems, recently proposed as non-orthogonal grid be nchmark problems. The system of discretized equations is solved effici ently with a non-linear multigrid algorithm, in which a robust line sm oother is implemented. Furthermore, another benchmark problem is intro duced and solved in which a 90-degrees change in grid line direction o ccurs.
