    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.

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.

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

BOILING-UP -- CRYOGENIC LIQUIDS -- KRAMERS-ZELDOVICH METHOD
Аннотация: The kinetics of spontaneous boiling-up of superheated binary solutions of cryogenic liquids is studied. Within the framework of the Kramers-Zeldovich method, an expression is obtained for the steady state rate of homogeneous nucleation in a solution that takes into account free-molecular and diffusion regimes of the substance supply to a growing bubble. Viscous and inertial forces are also taken into account in the study of the nucleus growth dynamics. The work of critical nucleus formation is determined within the framework of the Gibbs and van der Waals capillarity theories. The dependence of the surface tension of critical bubbles in the solution on their size is investigated. The temperature of attainable superheating and nucleation rates in superheated solutions of cryogenic liquids with complete or partial solubility of the components are determined by a method of lifetime measurement. The experiments were conducted in a wide range of pressures and solution concentrations. The measurement results are compared with the theory of homogeneous nucleation taking or not taking into account the size effect in nucleation. It has been found that, by taking into account the size dependence of the surface tension of a nucleus, better agreement between the theory and experiment is obtained. The boundary of essential instability of the solution, that is, the diffusion spinodal, is computed
