Abstract
This article theoretically investigates the acoustic waves propagation in bubbly liquids in the presence of diffusion mass transfer. Numerical calculations of the dynamics of pressure pulse in bubbly liquids are performed for different values of the vapor concentration. An increase the vapor concentration in the bubbles leads to a decrease in the propagation velocity of the low-frequency harmonics that make up the pulse and to an increase their attenuation due to the nature of the dependence of the phase velocity and attenuation coefficient on the vapor content in the gas bubbles.
