空化初生及其影响因素综述（英文）

A review on cavitation inception and its influencing factors

空化不仅是一种与流体压力变化有关的动态过程,而且在流体机械和其他工业设备中也普遍存在,尤其是在泵和水轮机中。该现象自出现至今一直被备受国内外专家学者的密切关注。同时在空化初生的影响因素这一问题上也存在一定的分歧。作为空化发生和发展的首个阶段,对于空化初生的研究始终是流体机械、船舶工程和国防工业建设领域的重要课题。鉴于上述分析,对空化初生的研究现状与其影响因素进行归纳总结,指出现阶段空化初生的主要研究方向并对未来研究趋势进行展望。

Cavitation is not only a kind of dynamic process related to the change in fluid pressure but also a universal and widespread phenomenon in fluid machinery and other industrial equipment,especially in pumps and hydraulic turbines.This phenomenon has attracted much attention of fellow^scholars since its emergence.Certainly,there are still some controversies in terms of influencing factors of cavitation.At the same time,as the first stage of the cavitation occurrence and development,the research on cavitation inception is always an important subject in the fields of fluid machinery,ship engneering and national defense industry construction.In light of the analysis mentioned above,the status quo of current research on cavitation inception is induced and its influencing factors are summarized.In addition,the existing main research directions of cavitation inception are pointed out and some trends and aspects of future research ar^explored and anticipated.
