    Attainable Superheat of Argon-Helium, Argon-Neon Solutions [Text] / V. G. Baidakov, A. M. Kaverin, V. N. Andbaeva // Journal of Physical Chemistry B. - 2008. - Vol. 112, № 41. - P12973-12975

ARGON
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.

NUCLEATION -- THEORY OF HOMOGENEOUS NUCLEATION -- BOILING
Аннотация: The results are given of experimental investigations of the kinetics of nucleation in gas-saturated helium-oxygen solutions. The temperature dependences of the mean lifetime of solution in the metastable (superheated) state are determined for fixed values of pressure of 1.171 and 1.667 MPa and for several values of concentration. The experimental data are compared with the theory of homogeneous nucleation in a macroscopic approximation with due regard for the dependence of the properties of the nuclei on their size. The dimensional effect is included within van der Waals' gradient expansion. The problems associated with the construction of the kinetic theory of boiling of gas-saturated solutions are discussed, and good agreement is ascertained between the experimental data and the theory of nucleation when the latter includes the dimensional effect

Аннотация: Method of measuring the lifetime of the superheated liquid was used to determine temperatures of the limit superheating of the solution of oxygen-nitrogen-helium. The method of calculating the properties of this solution (temperature of limit superheating, saturated vapor pressure, and density) based on the data on the properties of solutions of oxygen-helium and nitrogen-helium was proposed. The surface tension of the solution of oxygen-nitrogen-helium was determined in a special experimen

The surface tension γ and adsorption have been calculated from the obtained values of a2 employing, in addition, literature data on the density of the liquid and vapor phases of the respective solutions.

EXPLOSIVE CAVITATION -- HELIUM-SATURATED LIQUID -- THIN PLATINUM
Аннотация: The kinetics of explosive cavitation has been studied by experiment in helium-saturated liquid argon. Measurements have been made by the method of pulse heating of a solution on a thin platinum wire in a negative-pressure wave. The temperature dependence of cavitation strength has been traced, the effective values of the nucleation rate J and the derivative dlnJ/dT have been determined. It has been found that the dissolution of helium results in decreasing cavitation strength of argon. Satisfactory agreement between data of homogeneous nucleation theory and experiment with the use of capillarity approximation in the latter, though limiting stretches (superheats) attained by experiment are nevertheless systematically lower than calculated ones

SUPERSATURATED SOLUTIONS -- HOMOGENEOUS NUCLEATION -- SURFACE TENSION
Аннотация: The paper presents the results of experimental investigations of nucleation in helium-oxygen gas-filled mixtures. Temperature dependences of the mean lifetime of a mixture in the metastable (superheated) state have been determined, and nucleation rates have been calculated by experiments at fixed pressures of 1.171 and 1.667 MPa and at several values of concentrations. Experimental data are compared with results of the homogeneous nucleation theory in a macroscopic (capillary) approximation and with allowance for the dependence of the properties of nuclei on the curvature of their dividing surface. The size effect of nucleation is taken into account in the framework of the van der Waals, Cahn-Hilliard method. The equation of state of the mixture has been built, and the boundary of stability of homogeneous states, the diffusion spinodal, has been determined. The paper discusses the problems of building a nucleation theory for gas-filled mixtures and states a good agreement between theory and experiment at nucleation rates J similar or equal to 10(7) m(-1) s(-1) when the size effect in nucleation is taken into account

LIQUID -- SOLUTIONS -- INERTIAL FORCES
Аннотация: A theory of the spontaneous boiling-up of supersaturated liquid solutions, which allows for all major factors limiting growth of a nucleus, such as volatility of solution components, viscous and inertial forces, and diffusional supply of a substance to the bubble, is proposed. Two approaches to determining the work of critical nucleus formation, based on the Gibbs method of diving surfaces and the Van der Waals theory of capillarity, are reviewed. Experimental data on the kinetics of boiling-up of nitrogen-helium and oxygen-helium solutions are presented. The results of the experiments are compared to the theoretical approaches to the problem of nucleation in gassed liquids, developed by the authors
