ADSORPTION -- CAPILLARY CONSTANT -- DIFFERENTIAL CAPILLARY METHOD
Аннотация: The differential capillary method has been used to measure the capillary constant a2 of methane-helium solutions in the temperature range from 95 to 175K at pressures up to 4MPa. 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. Equations, which approximate the temperature, pressure and concentration dependences of a2 and γ, are proposed

MOLECULAR DYNAMICS METHOD -- ARGON-NEON -- LENNARD-JONES
Аннотация: The molecular-dynamics method has been used for calculating the density profiles of the mixture argon−neon, surface tension, and adsorption in systems of 4096−8957 Lennard−Jones particles at a reduced temperature T* = kBT/εα0.7 ± 0.01 and a pressure up to p* = pσα3/εα = 0.6, where σα and εα are parameters of the argon potential. The results of calculating phase-equilibrium parameters are compared with data for a single-fluid model of a solution. The paper discusses the applicability of an extended version of the van der Waals capillarity theory to the description of the surface tension of a gas-saturated liquid

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

ADSORPTION -- CAPILLARY CONSTANT -- SURFACE TENSION
Аннотация: The paper presents the results of measuring the capillary constant a2 and calculating the surface tension σ of ethane-methane solutions. Experimental data have been obtained in the temperature range from 93.15 to 283.15K at pressures from that of saturated vapors of pure ethane to 4MPa. Equations that approximate the temperature, pressure and concentration dependences of a2 and σ are suggested. The concentration dependence of the surface tension is described in the framework of models of an ideal and a regular solution. The relative adsorption has been calculated

HOMOGENEOUS NUCLEATION -- OXYGEN -- KRYPTON
Аннотация: The nucleation of the vapor phase in superheated nitrogen-helium liquid solutions was studied by lifetime measurements. The temperature dependences of the mean lifetime of metastable solutions were obtained at p = 0.5 and 1.0 MPa and several concentrations. The nucleation rate J was found to vary from 10(4) to 10(8) s(-1) m(-3). The adsorption of the high-volatility component on the metastable liquid-critical bubble boundary was shown to play a determining role in decreasing the temperature of the attainable solution super-heating as the solution concentration increased. The experimental data were compared with homogeneous nucleation theory. Systematic discrepancies were obtained; these discrepancies were related to the influence of the size effect on the surface tension of a nucleus and the work of its formation
