In freeflowpattern and submerged flow pattern, as long as flow movement meet the dynamic similar criterion can reach the similarity of spillway tunnel flow pattern;
在自由流和淹没流时，只要水流运动满足动力相似准则就可达到泄洪洞水流流态的相似；

This turbulence caused the flowpattern in the tunnel to be similar to the flowpattern in free air at a higher Reynolds number.
这种紊流使风洞内的流谱与在较高的雷诺数下自由气流中的流谱相似。

Moreover, flow distribution was also calculated by free-vortex flowpattern and compared with that by iso-reaction coefficient flow pattern. Relative evaluation …
