论文摘要
在本文中，我们基于图像方法提出了一个简化的理论模型，该模型预测了在自由界面和刚性壁之间产生的空化气泡后产生的微射流的方向。我们的理论预测已经通过一项彻底的实验研究来验证，在该研究中，脉冲激气泡到壁和自由表面的距离以系统的方式变化。此外，我们将预测扩展到角角的任意值，$π/（2n）$，$ n $ a自然数。目前的分析解决方案将有助于设计新策略，旨在防止固体基板上的气泡造成的破坏
In this paper, we present a simplified theoretical model based on the method of images that predicts the direction of the microjet produced after the implosion of the cavitation bubble created in between a free interface and rigid wall. Our theoretical predictions have been verified by means of a thorough experimental study in which the distances of the pulsed-laser cavitation bubble to the wall and the free surface are varied in a systematic manner. In addition, we extend the predictions to arbitrary values of the corner angle, $π/(2n)$ with $n$ a natural number. The present analytical solution will be useful in the design of new strategies aimed at preventing the damage caused by cavitating bubbles over solid substrates
