Abstract

We derive a simple formula for the lowest natural frequencies of an infinitely long bubble plume with arbitrary cross section. Expressions are derived in terms of bubble volume fraction and equivalent radius of the plume, and a criterion for the existence of collective modes is established. For the plume with the circular cross section, our analytical approach is validated with the results of previous studies and numerical solution.

气泡羽流的集合声学模式。

我们推导出了具有任意横截面的无限长气泡羽流的最低固有频率的简单公式。根据气泡体积分数和羽流等效半径推导出表达式，并建立了集体模式存在的标准。对于圆形截面的羽流，我们的分析方法与之前的研究结果和数值解法进行了验证。
