| 摘 要： | 采用光偏转测试系统对不同粘度液体中激光诱导的空泡脉动现象进行了实验研究,探测了不同粘度液体中空泡前3次脉动的全过程,分析了液体粘度变化对空泡动力学特性的影响.结果表明:液体粘度相同时,激光空泡的最大、最小泡半径和脉动周期均随脉动次数增加依次减小,且减小的幅度较大;液体粘度增加时,空泡的最大泡半径减小,而空泡的最小泡半径和生命周期则增加.

| Abstract: | The characteristics of cavitation bubble oscillation in glycerol-water mixtures with different viscosities are investigated by a sensitive fiber-optic sensor based on optical beam deflection.The maximum and minimum bubble radii and the oscillation times for each oscillation cycle are determined according to the characteristic signals.The experimental results show that these parameters during each oscillation decrease sharply for successive oscillations.Furthermore,the increase of viscosity decreases the max... |
