摘要
综述了高压水射流技术发展及应用过程，认为空化水射流是一种富有发展前途的高效新型射流．通过对空化水射流机理、空化数和冲击压力两个重要空化参数的分析，显示了空化射流的潜在优势．实验表明人工淹没空化射流具有较强的冲蚀效果，并克服了靶距范围的不足．简要介绍了该技术应用于火箭发动机内脏固体推进剂清洗工程的射流系统设计．
The development and application of high pressure water jet is conducted in this paper.It shows that cavitating water jet is a new type jet with great potential and good efficiency.The potential of cavitating water jet is further consided by analysing its mechanism,including two impotent cavitation parameters' cavitation number and impulse pressure.The experiments show anificial submerged cavitating jet has better erosion pthennance and longer standoff distance. Finally, the study on the cleaning work of solid propellant in the chamber of rocket engine by cavitating wade jet, is also introduced briefly.
