摘要：
We study the parallel numerical solution of the Navier-Stokes equations on a turbulent test case using the sparse grid combination method. This algorithmic concept is based on the independent solution of many problems with reduced size and their linear combination. We describe the algorithmic concept in a brief manner and we report on its application to turbulence simulation also. Statistical results on a pipe flow for Reynolds number Re-cl = 6950 are presented at different mesh refinements up to 25.10(6) grid points and compared to results obtained from other numerical simulations and physical experiments.
