水中两个气泡的声耦合
Acoustic coupling between two air bubbles in water
摘要:
两个气泡浸入水中的声耦合被清楚地证明。该系统是声学强制的,并且其响应被检测。实验结果证实,理论预测的本征模,分别对称和反对称,确实存在。它们的频率,作为气泡间距的函数测量,在10%的准确度内遵循理论估计。
英文摘要:
The acoustic coupling between two air bubbles immersed in water is clearly demonstrated. The system is acoustically forced, and its response is detected. The experimental results confirm that both theoretically predicted eigenmodes, respectively symmetrical and antisymmetrical, do exist. Their frequencies, measured as a function of the bubbles spacing, follow theoretical estimations within a 10% accuracy.
