Acoustic properties of overheated liquid with gas nuclei during temperature increasing

Abstract

Abstract The characteristics of the reflection and refraction of harmonic waves at its oblique incidence on an interface between a “pure” liquid and liquid with bubbles filled with a vapor–gas mixture have been studied. For the considered problem, we have obtained the dispersion equation and carried out a numerical analysis of the effect of the perturbation frequencies in the range 102–106 s–1 on the dependence of the angle of refraction on that of incidence for three equilibrium temperatures T 0. The dependence of the critical angle of incidence on the parameters of a two-phase system and the perturbation frequencies has been studied for the same reflection.
