Abstract

The paper considers the two-dimensional interaction between long wavelength (sound) and short wavelength (ultrasound) pressure perturbations in a rarified monodispersive mixture of a weakly compressible liquid with gas bubbles. The conditions are derived for which this interaction leads to singular focusing (explosive instability) of the ultrasound. A numerical study is made of the defocusing and singular focusing in a bubbly liquid. The effect of the long-wave-short-wave resonance on the development of two-dimensional perturbations is investigated.
