本文研究了膜与水中振荡气泡的相互作用。虽然这种气泡在弹性（相对较厚）边界附近的行为已经被几位作者研究过，但很少有人关注这种气泡在（薄）弹性膜附近的行为。对于膜，是曲率而不是偏转导致靠近气泡的流体中的压力积聚。由于物理学上的这种差异，不能确定可变形弹性边界附近的气泡相对于膜的动力学是否会表现出任何相似性。我们的目的是对后者进行系统的研究，这可以在未来的工作中加以利用（例如，在经常涉及弹性膜的生物医学应用中）。瞬态气泡与薄弹性膜的相互作用的实验观察和膜附近的气泡的动力学进行比较的边界元法模拟。泡沫是一种…
A study of the interaction between a membrane and a submerged oscillating bubble is presented. Though the behavior of such a bubble near an elastic (relatively thick) boundary has been studied by several authors, much less attention is focused on the behavior of such a bubble near a (thin) elastic membrane. For membranes, it is the curvature and not the deflection that is responsible for a pressure buildup in the fluid close to the bubble. Due to this difference in physics, it is not a certainty if the dynamics of bubbles near a deformable elastic boundary vis-a-vis a membrane would exhibit any similarity. Our intent is a systematic study on the latter, which can be exploited in future work (e.g., in biomedical applications where elastic membranes are often involved). Experimental observations of transient bubble interaction with a thin elastic membrane are presented and the dynamics of the bubble in the vicinity of the membrane are compared to the boundary element method simulations. The bubble is genera...
