在本文中，我们证明了振动气泡的清洗能力，使用高速摄像机的气泡行为和清洗过程的光学观察的基础上。结果表明，在初始汽泡溃灭后，形成了汽泡团。气泡群由一个主气泡和许多小气泡组成。此外，光学观察清楚地表明，这些微泡的振荡去除了粘合到载玻片表面的薄油墨膜。从气泡振荡和清洗效果之间的关系的分析，它被证实，清洗面积的增加与气泡振荡的振幅的增加，虽然有一个不良的相关性清洗面积和气泡振荡。此外，观察结果表明，从几十kPa到MPa的压力范围内的载玻片上产生的流体动力学现象，微射流和二次波的振荡气泡发射。我们的实验结果导致超声清洗技术的清洗机理的理解。
In this paper, we demonstrate the cleaning ability of oscillating bubbles, on the basis of optical observations of bubble behaviors and cleaning process using a high-speed video camera. It was shown that a bubble cluster was formed after the collapse of the initial bubble. The bubble cluster consisted of a main bubble and many small bubbles. In addition, optical observations clearly revealed that the oscillations of these microbubbles removed a thin ink film bonded to the surface of a slide glass. From the analysis of the relationship between bubble oscillation and cleaning effect, it was confirmed that the cleaned area increased with an increasing amplitude of bubble oscillation, although there was a poor correlation between cleaned area and bubble oscillation. Moreover, the observed results suggested that a pressure ranging from several tens kPa to MPa was generated on the slide glass by hydrodynamic phenomena; micro jet and secondary wave were emitted by the oscillating bubble. Our experimental results lead to the understanding of the cleaning mechanism in ultrasonic cleaning techniques.
