Аннотация:

The propagation of weak perturbations in the superheated air-water bubbly medium is studied when in addition to water vapor bubbles contain inert gas (air, for example) does not participating in phase transitions. The effect of the initial overheating and the initial volume content of bubbles on the evolution of harmonic waves is analyzed. It is established that in the case of perturbations from the low-frequency region, an increase in the initial volumetric gas content leads to an increase in the damping coefficient, and the phase velocity decreases significantly in this case.
