Ключевые слова (''Своб.индексиров.''): 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??

Заглавие : A method of controlled pulse heating: Applications
Место публикации : Journal of Engineering Thermophysics. - 2007. - Vol.16, №3. - С. 155-163
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): thermophysical properties --thermal stabilization --high-molecular fluids
Аннотация: This paper is devoted to the state-of-the-art and technical potentials of the pulse heating method for the thin wire probe created in the Ural thermophysical school for studying the kinetics of spontaneous boiling and the related phenomenon of liquid attainable superheating. Special attention is paid to the search for technical means for controlling the power of the probe heating in a pulse experiment with the thermophysical properties of the substance taken into account. Applications of three particular cases are considered: techniques for the constant heating power, the thermal stabilization of the pulse-heated probe, and cooling of the shock-heated probe for investigating the behavior of multicomponent and high-molecular fluids essentially superheated above the temperature of phase equilibrium and/or temperature of molecule thermodestruction in a quasi-static process. Opportunities for application of the method are presented, in particular, for fast detection of volatile admixtures (including their traces) in high-molecular fluids, e.g., in oils of power equipment

Заглавие : Attainable Superheat of Argon-Helium, Argon-Neon Solutions
Место публикации : Journal of Physical Chemistry B. - 2008. - Vol. 112, № 41. - С. 12973-12975
ББК : 53
Предметные рубрики: ФИЗИКА
Аннотация: The method of lifetime measurement has been used to investigate the kinetics of spontaneous boiling-up of superheated argonhelium and argon?neon solutions. Experiments were made at a pressure of p = 1.5 MPa and concentrations up to 0.33 mol% in the range of nucleation rates from 104 to 108 s1 m3. The homogeneous nucleation regime has been distinguished. With good agreement between experimental data and homogeneous nucleation theory in temperature and concentration dependences of the nucleation rate, a systematic underestimation by 0.250.34 K has been revealed in superheat temperatures over the saturated line attained by experiment as compared with theoretical values calculated in a macroscopic approximation. The revealed disagreement between theory and experiment is connected with the dependence of the properties of new-phase nuclei on their size.

Ключевые слова (''Своб.индексиров.''): kinetics--boiling-up--quantum nucleation
Аннотация: This review addresses the kinetics of spontaneous boiling-up of liquefied gases and their solutions. It discusses the theories of thermal and quantum nucleation in metastable liquids. The experimental methods for studying the nucleation kinetics are outlined. The experimental data on the attainable superheating temperature for cryogenic liquids and solutions of liquefied gases are presented in a wide range of pressures, including negative ones. The properties of new-phase nuclei near the boundary of attainable superheating are discussed. The kinetics of initiated and heterogeneous nucleation is considered. The experimental data on detection of quantum tunneling of nuclei are presented. The experimental data are compared with the theories of thermal and quantum nucleation
