Abstract

The theory of self-organization of bubbles in acoustic fields predicts formation and propagation of waves of self-induced acoustic transparency. This is a strongly nonlinear effect, which is a result of a two-way coupling of the sound field with the bubble distribution. We are challenging the theory with an experiment. Here, a homogeneous distribution of gas bubbles is first generated and then an ultrasonic field (∼100 kHz) is switched on. The ultrasound leads to a rapidly propagating bubble sheet away from the transducer which leaves a liquid almost free of bubbles behind the front. The dynamics is observed with a high-speed camera and analyzed. A simplified theoretical model of this acoustically-induced transparency is developed and numerical simulations for conditions of the experiment are performed. A comparison of the experimental data with the model shows a good agreement. The underlying physics of the problem is discussed.
