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

    Nucleation of liquid droplets and voids in a stretched Lennard-Jones fcc crystal [Electronic resource] / V. G. Baidakov, A. O. Tipeev // Journal of Chemical Physics. - 2015. - Vol. 143, № 12. - С. 124501/1-124501/11

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

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

    Characteristic features of the boiling of emulsions having a low-boiling dispersed phase [Electronic resource] / N. V. Bulanov, B. M. Gasanov // Journal of Engineering Physics and Thermophysics. - 2006. - Vol. 79, № 6. - P1130-1133

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.??
