实验表明，在不稳定的涡流场中，外部声激励将会对内部流场中的不稳定涡流产生影响，形成声涡相互耦合的感应性，声控的效果依赖于激励声波的大小和频率。本文从流体力学普遍方程出发，建立在单频声激励下，声场和流场相互耦合的理论模式。利用摄动方法，讨论了声涡相互耦合的感应性，从理论上论证了声激励存在声涡共振频率。
Experiments show that in an unstable vortex field, the external acoustic excitation will affect the unstable vortex flow in the internal flow field and form the acoustic vortex coupling coupling. The effect of sound control depends on the size and frequency of the excitation sound wave. In this paper, starting from the universal equation of fluid mechanics, a theoretical model of mutual coupling of sound field and flow field is established under single-frequency excitation. Using the perturbation method, the inductive coupling between acoustic vortices is discussed, and the acoustic vortex resonant frequency is demonstrated theoretically.
