Analog of Landau damping the problem of sound-wave propagation in a liquid with gas bubbles
Ryutov D. D.
It is shown that a small initial perturbation in a liquid with gas bubbles attenuates to the end even in the absence of any dissipative processes, owing to the transition of the sound-wave energy into the energy of the natural oscillations of the bubbles. Other examples are presented of macroscopic systems in which this effect, which is analogous to the Landau damping in plasma physics, in manifest.
