Summary

The parallel numerical solution of the Navier-Stokes equations with the sparse grid combination method was studied. This algorithmic concept is based on the independent solution of many problems with reduced size and their linear combination. The algorithm for three-dimensional problems is described and its application to turbulence simulation is reported. Statistical results on a pipe flow for Reynolds number Re cl = 6950 are presented and compared with results obtained from other numerical simulations and physical experiments. Its parallel implementation on an IBM SP2 computer is also discussed.
