摘要: 本文应用格子Boltzmann方法对具有挡板二维管道中的Karman涡街进行了数值模拟,采用并行计算模式得到了在不同雷诺数不同时间步的情况下的涡线图,计算结果较好地再现了已有的数值结果。
Abstract: In this paper, the lattice Boltzmann method is used to simulate the Karman vortex in the two-di- mensional pipe with baffle. The parallel scheme is used to obtain the vorticity contours in the case of different Reynolds numbers at different time steps. The calculated results reproduce the existing numerical results rather well.
