减速运动活塞表面空化的可视化研究

Study on the Surface Fluid Cavitation for a Decelerating Piston

通过实验研究了液体中作减速运动活塞表面的游移空化现象以及不同液体和不同导管长度对空化的影响，基于数字图象处理方法，对空化随时间发展进行了描述并对活塞表面空化原因及有关现象进行了分析。

Fluid travelling cavitation on the surface of a decelerating piston is investigated experimentally, and the effect of tube length and fluid property on the phenomena is also examined. By using the technique of digital image processing, the process of cavitation developing in experiments is recorded. Some analyses are given.
