Abstract

The propagation of acoustic waves in two-fraction liquid mixtures containing vapor-gas bubbles of different dimensions and composition with phase transitions in each fraction is investigated. The system of differential equations of the mixture motion is presented and the dispersion equation is derived. The evolution of weak pulsed pressure disturbances in the mixture is numerically investigated. The effect of phase transitions in each fraction of the disperse phase on the evolution of a small-amplitude pressure pulse is shown.
