Acoustic waves in liquids with polydisperse gas bubbles. Comparison of theory and experiment

A mathematical model describing the propagation of acoustic waves of different geometry in two-fraction mixtures of a liquid with polydisperse gas bubbles of different composition is presented. A system of differential equations for the perturbed motion of the two-phase mixture is formulated and a dispersion relation is obtained. The theory developed is compared with known experimental data, including those for a near-resonance bubble frequency.
