摘要:: 空化空蚀现象、特征和机理的深入了解和认识,对于计算确定空化诱生荷载、预报空化空蚀危害等方面都有重要作用。本文系统地研究了作者根据水利工程中交汇水流和横轴漩涡空化空蚀破坏实例而设计的垂直汇流实验装置中空化发生、发展的一系列空化现象和特征,以初生空化和阻塞空化作为空化发展的两个重要性态转变指标,对空化的整个发生、发展和演变过程提出了一种新的分级方法,并且对垂直汇流中的各空化状态以10~(-3)秒速度拍摄了照片。本文的工作对其它空化源空化空蚀机理的研究有参考价值。

Abstract:: The in -depth understanding and understanding of the phenomenon, characteristics and mechanisms of airization, and has an important role in calculating to determine the hazards of emptiness and induction of loads and predicting the hazards of empty erosion. This article systematically studies a series of vacuum phenomena and characteristics designed and developed by the author designed and developed by the author designed and developed according to the exchanges of waterflow and horizontal axis vortex vortex. It uses two important transformation indicators for newbornness and obstruction as the development of empty development. The state of each vacant state was taken at a speed of 10 ~ (-3). The work of this article has a reference value for the research of other vacuum and empty erosion mechanisms.
