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

HELIUM
Аннотация: The method of lifetime measurement has been used to investigate the nucleation of the vapor phase in a superheated liquid nitrogen–helium solution. Temperature dependences of the mean lifetime of a metastable solution have been obtained in experiments at pressures p = 0.5, 1.0 MPa and several values of the mixture concentration. The nucleation rate J has been calculated. It varied in experiments from 104 tо 108 s?1 m?3. The results of experiments are compared with homogeneous nucleation theory. The paper deals with the size effect on the surface tension of a nucleus and the work of its formation.

CLASSICAL NUCLEATION THEORY -- METHOD OF LIFETIME MEASUREMENT -- ETHANE-NITROGEN SOLUTION
Аннотация: The method of lifetime measurement is used to investigate the kinetics of spontaneous boiling-up of ethane-nitrogen solutions. Superheating temperatures Tn of solutions have been determined in experiments at pressure p = 1.0, 1.6 MPa and nitrogen concentration in ethane x = 0.5, 1.5 mol% in the nucleation rate range J = 1 × 104-2 × 108 s-1 m-3. At J > 3 × 106 s-1 m-3 one can observe a satisfactory agreement between experimental data and homogeneous nucleation theory with respect to the temperature dependence of the nucleation rate and a systematic disagreement in the superheating temperature. At x = 0.5 mol% attainable superheating temperatures achieved by experiment coincide within the experimental error with theoretical values, and at x = 1.5 mol% exceed them by approximately 1.7 K. It is shown that one possible reason of such "excess superheating" of a solution beyond the theoretical value of Tn may be the absence of adsorption equilibrium at the critical bubble-ambient solution interface

NUCLEATION -- METHOD OF CONTINUOUS PRESSURE LOWERING -- HETEROGENEOUS NUCLEATION -- SUPERHEATING
Аннотация: The method of continuous pressure decrease has been used to investigate limiting (attainable) stretches of ethane–nitrogen solutions. Experiments were conducted at temperatures of 260, 266, 270, and 276 K and at nitrogen concentrations in the solution of 0.5 and 1.5 mol%. Pressure decrease rates were taken in the range 0.01–0.1 MPa/s. Distribution functions of liquid boiling-up events in dependence on pressure have been obtained allowing one to determine the most probable (attainable) pressures of liquid boiling-up and the nucleation rate. The results are interpreted in terms of nucleation thermodynamics and kinetics in liquids on a solid surface containing inclusions that initiate the boiling-up processes. It is shown that for realizing homogeneous nucleation it is not necessarily required that the wettability is close to the ideal one. The reasons for the discrepancy between experimental data and predictions of homogeneous nucleation theory at nucleation rates J < 3 × 106 s−1 m−3 are discussed.
