Abstract

Dynamics of pressure waves in a flat channel with a sloping boundary between bubbly and pure liquids is investigated. It is shown that, at the boundary between water–air mixture and water, reflection of waves incident on the boundary from the side of air–water mixture is analogous to reflection from a rigid wall, which leads to interference of waves. It is found that, with an increase in the volume content of bubbles and decrease in the bubble radius, the maximum wall pressure amplitude of the resulting wave increases.

气泡楔形中压力波聚焦的条件

摘要

研究了气泡与纯净液体之间边界倾斜的平坦通道中压力波的动力学。结果表明，在水-空气混合物和水之间的边界处，从空气-水混合物侧面入射到边界上的波的反射类似于刚性壁的反射，从而导致波的干扰。发现随着气泡的体积含量的增加和气泡半径的减小，所产生的波的最大壁压力振幅增大。
