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 computer study of the absorption of infrared radiation by systems of molecular clusters
Место публикации : High Temperature. - 2006. - Vol. 44, № 6. - С. 932-940
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): molecular clasters
Аннотация: The method of molecular dynamics is used to investigate the process of absorption of Nsub2/subO and CHsub4/sub molecules by water clusters and to determine the frequency spectra of permittivity for systems consisting of clusters mixed in different ratios, namely, (Hsub2/subO)subn/sub, (Nsub2/subO)subi/sub(Hsub2/subO)sub10/sub, and (CHsub4/sub)subi/sub(Hsub2/subO)sub10/sub. IR-radiation absorption spectra for these systems are calculated and analyzed; the radiation power scattered by these systems and the tangent of dielectric loss angle are determined. The inclusion of anharmonicity of phonon oscillation makes it possible to explain the origin of characteristic frequencies appearing in IR spectra of mixtures of cluster systems. The capture of molecules of greenhouse gases by an ultradisperse aqueous medium affects the ability of this medium to absorb terrestrial radiation, i.e., reduces the greenhouse effect.

ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): sound velocity--heavy water--superheating
Аннотация: The review presents the results of experimental investigations of nucleation in superheated light and heavy water in the range of nucleation rates from 104 to 1029 s−1m−3. A study is performed of the kinetics of crystallization of droplets of superheated water and amorphous water layers. Measurements have been made of the density, sound velocity, dielectric constant of light and heavy water in the vicinity of the phase equilibrium line with deep entry into the region of metastable (superheated) states. The local and integral characteristics of streams of boiling-up water flowing out into the atmosphere through a short channel have been investigated. One can see the determining role of a vapor phase in such a process at a temperature above 0.9T c , where T c is the temper-temperature at the critical point

Заглавие : Boiling up of jets of superheated ethanol-water solutions
Место публикации : Journal of Engineering Thermophysics. - 2007. - Vol.16, №4. - С. 244-248
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): evolution of the shapes --superheated aqueous solutions --low-boiling liquid
Аннотация: The stability and evolution of the shapes of jets of strongly superheated aqueous solutions of ethanol flowing out of a high-pressure chamber are experimentally investigated at various initial parameters. It has been found that a low-boiling liquid causes shifting to lower temperatures of the boundaries between various kinds of boiling-up jets, such as cylindrical, conical, and open. Large-scale pulsations of the jet shapes are observed in the temperature range from 454 to 484 K, where the jet completely breaks down. The conditions for the formation of large-scale low-frequency pulsations with a power spectrum diverging inversely proportional to the frequency f (1/f spectra) have been revealed. Such fluctuations prove that the flow is unstable and large-scale low-frequency ejections are possible

Аннотация: The results of the experimental investigations on the heat transfer of thin wires with water/oil and ether/water emulsions are given. The temperature of normal oil boiling is not lower than 340°C. A considerable delay in the crisis of bubble boiling is obtained for both emulsions, and is particularly noticeable for the ether/water emulsion. In the latter case the coefficient of connective heat transfer and the density of heat flux substantially exceed the corresponding values for pure initial liquids in the entire investigated range of temperatures (from 20 to 230°C) and pressures (from 0.1 to 3.6 MPa)

Аннотация: The heat transfer from thin wires to emulsions with a disperse phase formed from a liquid whose boiling temperature is much lower than the boiling temperature of the disperse medium was investigated. Experiments were conducted at atmospheric pressure on vertical and horizontal wires from 50 to 100 ?m in diameter with n-pentane/glycerine, diethyl ether/water, and freon-113/water and water/oil emulsions.??It was possible to describe the experimental data obtained by one analytical dependence Nu = AArPrM?1[1 ? exp(?JVt)]. The dependence presented was obtained from the proposed model of the chain branched activation of boiling centers in droplets of a superheated liquid. In this case the coefficient J acquires the meaning of the activation rate of these centers.??

Ключевые слова (''Своб.индексиров.''): 3d model--evaporation--flat evaporator
Аннотация: A 3D model has been developed for investigating heat and mass transfer in a flat evaporator of a copper-water loop heat pipe. It takes into account heat-transfer processes in the active zone, the barrier layer of the wick, the wall and the compensation chamber. The problem was solved by the finite difference method with the use of a nonuniform grid adapted to the configuration of the flat evaporator and its geometric peculiarities. Investigations have been carried out for understanding the effect of the heating zone size on heat distribution in the evaporator. The heating area was 9 cm 2 with a uniform heat supply and 1 cm 2 with a concentrated one. Numerical simulation has been performed for a heat load range from 20 to 1100 W. Data have shown that a decrease in the heating area at a fixed heat load results in both increasing temperature on the evaporator wall under the heater and local wick draining in the active zone. The results of the model have been verified using results of experimental tests.

Ключевые слова (''Своб.индексиров.''): evaporation--flat evaporator--mathematical model
Аннотация: This paper presents a three-dimension mathematical model of a flat evaporator of a loop heat pipe which takes into account the peculiarities of the evaporator configuration and the specific character of a one-side heat load supply. All the main structural elements of the evaporator, such as its body, wick, vapor-removal grooves, barrier layer and compensation chamber, are included in the model. The intensity of heat-exchange processes during evaporation in the active zone is determined by local drops between the temperature at the wick surface and the vapor temperature. The effects of drying the wick in the evaporation zone are also taken into account. The problem was solved by a numerical method. The results of calculations are presented for a copper evaporator and water as a working fluid in the heat load range from 20 to 1100 W. A comparative analysis of calculated and experimental data has been made

Ключевые слова (''Своб.индексиров.''): compensation chamber--flat evaporator--heat-and-mass transfer--loop heat pipes
Аннотация: A three-dimensional heat-and-mass transfer model of a flat evaporator of a loop heat pipe has been developed for investigating heat-and-mass in a compensation chamber filled with a liquid. Numerical simulation was implemented using EFDLab® software package in order to predict the temperature distribution of the flat evaporator of a copper-water LHP (loop heat pipe) as well as the flow streamline and velocity field in the compensation chamber as a function of heat load. A computer simulation makes it possible to evaluate the heat exchange at the inner surface of the compensation chamber. Heat exchange data were used as a boundary condition in researching the problem of the drying effect of a wick and a transformation of the evaporating front in the active zone of the flat evaporator. © 2013 Elsevier Ltd.
