The dynamics of electrochemically produced hemispherical bubble at solid-liquid interface is investigated experimentally. Time-resolved photography is applied to measure the position of bubble wall as a function of time. By means of stroboscope schlieren photography with 1 μs exposure time it is shown that the development of instabilities of the bubble shape are general feature of the bubble dynamics in contact with the solid boundaries. The acoustic transients emitted after cavitation bubble collapse were registered with the laser beam deflection technique. Duration of the transient of 50–60 ns enables to estimate maximum pressure as 2.5 kbar, when the maximum bubble radius is 1 mm.

与固体边界接触的半球空化气泡的坍缩动力学

实验研究了固液界面电化学产生的半球气泡的动力学。时间分辨摄影用于测量气泡壁随时间变化的位置。通过曝光时间为 1 μs 的频闪仪纹影摄影表明，气泡形状不稳定性的发展是与固体边界接触的气泡动力学的一般特征。使用激光束偏转技术记录空化气泡破裂后发出的声瞬变。当最大气泡半径为 1 mm 时，50–60 ns 的瞬态持续时间可以估计最大压力为 2.5 kbar。
