Заглавие : 1/f Fluctuations under acoustic cavitation of liquids
Место публикации : Physica A. - 2006. - Vol.364. - С. 63-69
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): self-organized criticality--acoustic cavitation--nonequilibrium conditions
Аннотация: A regime of a generation of fluctuations with 1/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/f behavior of power spectra and scale-invariant distribution functions of fluctuations. The results of numerical simulation agree qualitatively with the experimental data

Заглавие : Attainable superheating of liquefied gases and their solutions : review
Место публикации : Fizika Nizkikh Temperatur. - 2013. - Vol.39, №8. - С. 835-862
Примечания : Bibliogr. : p. 861-862 (87 ref)
ББК : 53

Ключевые слова (''Своб.индексиров.''): cavitation--cryogenic liquids --meta-stable state
Аннотация: The review is mainly concerned with the kinetics of spontaneous boiling-up of liquefied gases and their solutions. It examines the theories of thermofluctuation and quantum nucleation in metastable liquids. The methods of experimental investigation of nucleation kinetics are given. The experimental data on temperature of attainable superheating of cryogenic liquids and solutions of liquefied gases are presented for a wide range of pressures, including negative ones. The properties of new-phase nuclei near the attainable super-heating boundary are discussed. The kinetics of initiated and heterogeneous nucleation is considered. The experimental data on detection of quantum tunneling of nuclei are given. Experimental data are compared with the theories of thermofluctuation and quantum nucleation

Заглавие : Boiling-up of liquid argon at high superheatings under the impact of weak ultrasonic fields
Место публикации : Thermophysics and Aeromtchanics. - 2011. - Vol.18, №1. - С. 31-36
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): nucleation --krypton
Аннотация: The technique of lifetime measurement for metastable liquid and continuous depressurization technique were applied for study of kinetics of spontaneous cavitation in superheated liquid argon under impact of weak ultrasonic fields. It was demonstrated that acoustic cavitation may occur through the mechanism of homogeneous generation of vapor phase or through "swinging" of vapor bubbles generated by high-energy particles and/or other kinds of initiative factors. The thresholds of acoustic cavitation are described by the theory of homogeneous nucleation

Заглавие : Boiling-up of superheated liquid argon in an acoustic field
Место публикации : Journal of Physics : Condensed Matter. - 2009. - Vol.21, №46. - С. Article Number 465103
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): nucleation -- state
Аннотация: The method of lifetime measurement has been used to investigate spontaneous cavitation kinetics in superheated liquid argon in weak acoustic fields. It is shown that acoustic cavitation may proceed both by the mechanism of homogeneous nucleation of the vapor phase and by way of 'build-up' of vapor bubbles generated by high-energy particles or the action of some other external factor. Acoustic cavitation thresholds are adequately described by homogeneous nucleation theory
