Abstract

A two-dimensional interaction between long-wave (sound) and short-wave (ultrasound) pressure perturbations in a rarefied monodisperse mixture of a weakly compressible liquid with gas bubbles is considered. The conditions at which this interaction leads to a singular focusing (an explosive instability) of ultrasound are determined. A numerical study of the defocusing and the singular focusing in a bubbly liquid is carried out. The effect of the long-wave-short-wave resonance on the development of two-dimensional disturbances is studied.
