| Abstract: | The flow around two circular cylinders in various arrangement in high Reynoldsnumbers is numerically simulated based on vortex method, which are arranged in side by side and staggered. The results are similar to the experimental ones. Strouhal number, the lift coefficient and the drag one are in agreement with the experimental results, too. |
