Abstract

A regime of a generation of fluctuations with 1/f1/f power spectra under cavitation of liquids in an ultrasonic field has been found experimentally. The acoustic cavitation is accompanied by the formation of various spatial structures and scale-invariant distribution functions of fluctuations. It has been shown that local fluctuations can have non-Gaussian distribution.A two-dimensional distributed parameter system of stochastic equations describing interacting nonequilibrium phase transitions has been investigated numerically. It has been shown that the system in a wide range of changing initial conditions and the intensity of external noise is characterized by the 1/f1/f behavior of power spectra and scale-invariant distribution functions of fluctuations.The results of numerical simulation agree qualitatively with the experimental data.
