Oblique Incidence of an Acoustic Wave on a Layer of Bubbly Liquid

Consideration has been given to the problem of oblique incidence of an acoustic wave on a two-layer medium containing a bubbly-liquid layer. For the mixture ″water–water with air bubbles–water,″ the authors have calculated the coefficients of reflection and transmission of the wave as functions of the angle of incidence. Mixture parameters at which the reflection and transmission coefficients take on extremum values have been found and illustrated. A comparison has been made of the transmission coefficient and theoretical and experimental results of other authors. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
