The features of reflection and refraction of harmonic waves at the interface between
a ”pure“ liquid and a liquid with bubbles with a vapor-gas mixture under direct and
oblique incidence are studied. A numerical analysis is made of the effect of the initial
volumetric gas content
Problem: To study the dynamics of weak perturbations in a liquid with vapor and gas bubbles.
Methods: The solution of the problem is sought in the form of a damped traveling wave. From the condition for the existence of a solution of this form, taking into account the effects of acoustic discharge of bubbles, a dispersion equation is written out.
In a study was determined:
1. When the initial volumetric gas content varies from
2. With a decrease in the equilibrium radius of the bubbles
