Summary of study on ogee-section cavitation in longtaitou spillway tunnels;
龙抬头泄洪洞反弧段空化空蚀研究综述
Base on the previous research since 1981,this paper has given a brief introduction and comments on cavitation research of ogee-section in spillway tunnels.
根据国内外大量的工程实例,在前人研究的基础上,系统总结了龙抬头泄洪洞反弧段空化特性和空蚀成因,同时对反弧段的掺气减蚀和反弧段抗蚀体型的现有成果进行了综述,指出关于体型优化和掺气设施研究,数值实验具有花费少、适应能力强、提供的流场资料详细、便利方案选择等优点。
Therefore, it is very important to study sidewall aeration for safe operation of the ogee spillway tunnel.
高水头龙抬头式明流泄洪洞发生空蚀的部位一般位于反弧末端下游边墙及底板上,因此研究该部位的掺气减蚀设施具有十分重要的应用价值。
