Features of the Transmission of an Acoustic Wave Through a Multilayer Medium Containing Bubbly Liquid

The problem of the propagation and reflection of an acoustic wave in a liquid containing two layers of a multifractional bubbly liquid and a layer of pure liquid between them is considered. The angle of incidence of the wave on the plane surface of the three-layer region can be arbitrary, the layers of the bubbly liquid are moving. The coefficients of transmission and reflection of the wave through the layered region are determined in the case when water is taken as a liquid. The dependencies of these coefficients on the volume content of bubbles, the radius of the bubbles, the velocity of the layer movement, the thickness of the bubbly layer and the angle of incidence of the wave are established.
