HEAT TRAHSFER
Аннотация: The results are given of a theoretical investigation of heat transfer from thin wires to emulsions in which the disperse phase is low-boiling compared to the dispersion medium. A special feature of heat transfer to such emulsions is observed in the mode of nucleate boiling, when only the droplets of the disperse phase of emulsion are boiling. The transition from the convective mode of heat transfer to nucleate boiling requires high values of temperature gradient ? T = T W ? T 0 at which the temperature of the heat-transfer surface T W is higher than the temperature T S of saturated vapors of the disperse phase by 100 °C and more. Here, T 0 is the temperature of the heat-transfer agent away from the heat-transfer surface. Note that, for pure liquids and solutions, the value of delay of the beginning of boiling ? T i = T W ? T S as a rule does not exceed 1–5 °C. Another feature of heat transfer to the emulsions being treated is a wide temperature range of the mode of nucleate boiling (over 100 °C); the upper limit of this temperature range is defined by the temperature of transition to film boiling of the dispersion medium of the emulsion being investigated that has already boiled by this instant of time. The value of delay of the beginning of boiling is affected significantly by additions of surfactants and adsorbents.

LIQUID CRYOGENIC -- STATE METASTABLE -- STATE SUPERHEATED -- DEPENDENCE OF TEMPERATURE -- NUCLEATION -- p-PROPERTIES -- rho-PROPERTIES -- T-PROPERTIES -- ULTRASOUND VELOCITY
Аннотация: The results of an experimental investigation of cryogenic liquids in a metastable (superheated) state are considered. Data are presented on the maximum attainable superheat temperature of typical cryogenic liquids from atmospheric to close to critical pressures. The nucleation mechanism and the influence of factors that induce boiling on the attainable superheat of liquids are discussed. The results of experiments are compared with theory. Data on the thermodynamic properties (P, rho, T properties, heat capacity, ultrasonic velocity and attenuation, volume viscosity) of cryogenic liquids in a metastable liquids is discussed. Explosive boiling phenomena connected with large superheats of cryogenic liquids are considered, and the discharge of cryogenic liquids through short tubes and the heat interaction of cold liquid droplets with a hot surface are investigated

BOILING
Аннотация: The results of investigation of heat transfer from thin wires to a boiling emulsion, the dispersed phase of which is formed from a liquid with a boiling temperature much lower than the boiling temperature of the dispersion medium, are presented. Two variants of boiling of such an emulsion are possible: boiling of the dispersed phase alone and simultaneous boiling of the dispersed phase and dispersion medium. In the present work, only the first variant has been studied; it is distinguished by the following most important features: high superheat of the dispersed-phase droplets ?Tsup of the emulsion and a wide temperature range of bubble boiling (50–200°C). For conventional heat carriers (pure liquids and solutions), the value of ?Tsup does not exceed 1–10°C, with the bubble-boiling interval lying within the range from 5 to 20°C.

BOILING -- NUCLEATION SITE -- HEAT TRAHSFER -- ACTIVATION OF NUCLEATION SITES -- SUPERHEATED LIQUIDS
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.??

EFFERVESCENCE EXPLOSIVE -- DISPERSE-PHASE DROPLETS -- EMULSIONS
Аннотация: A method and an experimental setup for dispersion analysis of emulsions based on overheating and explosive effervescence of disperse-phase droplets are described. Formulas are derived and a procedure for determining the fitting parameters for a description of the dispersive composition of an emulsion is given. The maximum count rate was about 500 droplets per second for droplet diameters ranging from 5 to 200 mu m. The method can be automated to handle high-viscosity, opaque, unstable, and heavily contaminated emulsions

MOLECULAR DYNAMICS SIMULATION -- METASTABLE LENNARD-JONES
Аннотация: The method of molecular dynamics simulation has been used to investigate the phase decay of a metastable Lennard-Jones face-centered cubic crystal at positive and negative pressures. It is shown that at high degrees of metastability, crystal decay proceeds through the spontaneous formation and growth of new-phase nuclei. It has been found that there exists a certain boundary temperature. Below this temperature, the crystal phase disintegrates as the result of formation of voids, and above, as a result of formation of liquid droplets. The boundary temperature corresponds to the temperature of cessation of a crystal–liquid phase equilibrium when the melting line comes in contact with the spinodal of the stretched liquid. The results of the simulations are interpreted in the framework of classical nucleation theory. The thermodynamics of phase transitions in solids has been examined with allowance for the elastic energy of stresses arising owing to the difference in the densities of the initial and the forming phases. As a result of the action of elastic forces, at negative pressures, the boundary of the limiting superheating (stretching) of a crystal approaches the spinodal, on which the isothermal bulk modulus of dilatation becomes equal to zero. At the boundary of the limiting superheating (stretching), the shape of liquid droplets and voids is close to the spherical one

ATMOSPHERIC WATER -- DYNAMIC CALCULATIONS -- DYNAMIC CALCULATIONS
Аннотация: Molecular-dynamic calculations are used for analyzing the vapor quality of water monomers, clusters, droplets, and crystals in the Earth atmosphere. It is demonstrated that the integral intensity of absorption of infrared radiation for the initial series of water clusters does not increase with their size and stays smaller than the respective characteristic for free water molecule. The anti-greenhouse effect developed by clusters is defined as the difference between the greenhouse effects exhibited by free molecules of water making up the clusters and by the clusters proper. The value of anti-greenhouse effect is 3.6 K, and the greenhouse effect of atmospheric water clusters is estimated at 1.1

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
