CHARACTERISTIC FEATURES OF SOUND PROPAGATION IN A WARM BUBBLE-LADEN WATER

The propagation of weak disturbances in a water–air bubble medium has been studied under the conditions when in addition to the gas (e.g., air) undissolved in water the bubbles contain steam that can convert into water in the process of mixture motion. The air contained in the bubbles will in this case exert diffusion resistance and infl uence the intensity of phase transitions in the steam–water system. The infl uence of the initial parameters of a two-phase water–bubble mixture (volume content of phases, dispersed phase size, water temperature) on the evolution of harmonic waves in a bubble liquid has been analyzed.
