研究了稀疏网格组合方法并行求解Navier-Stokes方程的问题。这个算法的概念是基于许多问题的独立解决方案，减少规模和他们的线性组合。三维问题的算法进行了说明，并报告其应用湍流模拟。给出了雷诺数Re Cl = 6950的管流的统计结果，并与其它数值模拟和物理实验结果进行了比较。本文还讨论了它在IBM SP2计算机上的并行实现。
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.
