Abstract

The effects of the velocity distribution function of the bubbles on the propagation of waves in bubbly liquids are investigated. By linearizing the equations of motion, a dispersion relation which describes the propagation of the waves is obtained. The approximate solution of this relation indicates that the phase velocity is modified by the finite width of the distribution function. Furthermore, it is demonstrated that the waves are damped via a nondissipative collective mechanism. This damping can be observed only by the kinetic approach.
