摘要
通过压电陶瓷(PZT)水听器获取了液体中激光空泡脉动辐射的声波,并计算了激光空泡在第1次脉动过程中泡内的含气量,结合空泡含气量对空泡最大半径及脉动周期影响的分析,进而分析了含气量对空泡声波频谱特性的影响。分析结果表明:激光空泡第1次脉动过程中泡内的含气量随着作用激光能量的增加而增加,含气量的多少将直接影响空泡运动的剧烈程度;含气量越多,空泡脉动越缓慢,脉动周期越长,空泡脉动辐射声波的峰值频率有向低频移动的趋势。
Abstract
Laser-induced cavitation bubble collapse sound waves in liquid are measured by the PZT hydrophone, and the bubble content of laser-induced cavitation bubble during the first oscillating cycle is calculated. In combination with the analysis of the effect on the maximum bubble radius and oscillating duration of the bubble content, the effect on sound wave spectrum properties of the bubble content is investigated. The results indicate that the bubble content increases with the increase of laser energy. The bubble content influences the intensity of bubble collapse, and larger bubble content leads to shorter oscillating duration. Moreover, the peak frequency decreases with the increase of the bubble content.
