Abstract: The paper presents the results of studying the dynamics of a wave signal as it passes through gas-vapor bubble “screens” in a liquid, taking into account heat and mass transfer at the interface in the acoustic approximation. On the basis of numerical calculations using the fast Fourier transform method, wave patterns for pressure impulses are obtained and the influence of various parameters of the state of a liquid with vapor-gas bubbles on the reflection and transmission of acoustic waves through the “curtain” is studied.

Keywords: acoustic waves, vapor-gas bubbles, mass concentration vapor in bubbles, diffusion coefficient, thermal conductivity.
