摘要
综述一个多世纪以来,有压输水管道系统中有关气体释放、空穴流及液柱分离、计算分析方法、水锤防护及实验研究等方面的主要研究进展,并提出还需对气液两相瞬变流基本理论、空气进排气阀的特性、截留气团的动态特性和动力特性、实际工程优化设计理论等诸多方面进一步研究.
Advances are summarized in the research of gas release, cavitation flows and column separation, waterhammer protection, and methods for their calculation and experiments. It is suggested that a further study should be performed on the basic theory of gasliquid twophase transient flow, the characteristics of air valves, and dynamic state of trapped air, and on the theory of optimal design of projects.
