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

1/f-NOISE -- FLUCTUATIONS -- FLICKER NOISE
Аннотация: Thermal fluctuations under the transition from nucleate to film boiling of water on a wire heater and fluctuations of jet form during an outflow of superheated liquid from a pressure vessel were experimentally investigated. It has been found that power spectrum of the fluctuations has got a low frequency component corresponding to a 1/f law (flicker noise).??The effect given is connected with the occurrence of nonequilibrium phase transitions in the systems: a crisis of heat transfer under the transition from nucleate to film boiling and a crisis of a flow in boiling-up of superheated liquid jet??

    1/f noise at a critical nonequilibrium phase transition [] / V. P. Koverda, V. N. Skokov, V. P. Skripov // JETP Letters. - 1996. - V.63, Is.9. - С. 775-779

1/f-NOISE
Аннотация: The generation of 1/f noise is demonstrated experimentally in a system consisting of a superconducting film carrying a transport current in contact with a boiling liquid coolant. It is found that wide-band 1/f noise with a large amplitude of the fluctuations is observed over a wide range of parameters. This noise is attributed to the fact that the sub-systems in contact have the same character of the relaxational dependences delta T(t)similar to t(-1/2)

1/f-NOISE -- NONEQUILIBRIUM PHASE TRANSITIONS -- HIGH-TEMPERATURE SUPERCONDUCTOR -- BOILING -- STOCHASTIC EQUATIONS -- FILMS
Аннотация: We present the results of experimental study of an intensive source of wide-band 1/f noise whose generation appears in a system of two interacting nonequilibrium phase transitions. Such a process has been realized in the region of superposition of a superconductor-normal conductor phase transition on a liquid-vapor crisis transition in a boiling cooler. A mathematical model describing phase transitions in a dynamical system with two interacting order parameters, converting "white" noise into two stationary stochastic processes with 1/f and 1/f(2) spectra has been suggested. The properties of model oscillations with 1/f spectrum are qualitatively adequate to those observed in experiment. The characteristic difference of model oscillations with a 1/f(2) spectrum from classic random walks has also been noted

STOCHASTIC RESONANCE -- HARMONIC EXCITATION -- WHITE NOISE
Аннотация: A new behavior of two-dimensional system equations has been discovered upon stochastic resonance: at low frequencies of the harmonic excitation and increasing intensity of the white noise, the motion of the system is limited to two mutually perpendicular directions. In this case we obtain an anisotropic stochastic resonance. With further increase in the intensity of the white noise in the system, one can observe a normal stochastic resonance in which an increase in the intensity of fluctuations in the frequency range measured is blurred by directions

SOLID METALS
Аннотация: Arc current fluctuations between a solid metal electrode and a liquid melt of alkaline carbonates at atmospheric pressure are measured. Arc current fluctuation power spectra are determined from the measurement data. It is shown that the fluctuation power is inversely proportional to the frequency (1/f-fluctuations). The fluctuations have a normal Gaussian distribution. The observed 1/f fluctuations exhibit scale invariance.
