Acoustics and staility of a superheated liquid with gas bubbles

The propagation of weak disturbances in a superheated water-air bubble medium is considered in the case where the bubbles contain, in addition to water vapor, an inert gas (e.g., air) which is not involved in phase transitions. Maps of stability zones of the investigated systems depending on the degree of superheating of the liquid are constructed. The influence of the initial degree of superheating on the evolution of harmonic waves is analyzed. For unstable systems, the dependence of the increment on bubble radius with increasing degree of water superheating is studied
