Collective self-effect of sound in a liquid with gas bubbles
Kobelev Yu. A., Ostrovskii L. A.
A new mechanism for a self-effect of sound in a liquid with gas bubbles is examined. The effect results from an average motion of the gas bubbles over the period of the sound wave and from the coalescence of the bubbles under the influence of the radiation-pressure force and the hydrodynamic interaction of the bubbles in the acoustic field.
