Аннотация: In the theoretical interpretation of the kinetics of first-order phase transitions, thermodynamic concepts developed long ago by Gibbs are widely employed giving some basic qualitative insights into these processes. However, from a quantitative point of view, the results of such analysis, based on the classical Gibbs approach and involving in addition the capillarity approximation, are often not satisfactory. Some progress can be reached here by the van der Waals and more advanced density functional methods of description of thermodynamically heterogeneous systems having, however, its limitations in application to the interpretation of experimental data as well. Moreover, both mentioned theories—Gibbs’ and density functional approaches—lead to partly contradicting each other’s results. As shown in preceding papers, by generalizing Gibbs’ approach, existing deficiencies and internal contradictions of these two well-established theories can be removed and a new generally applicable tool for the interpretation of phase formation processes can be developed. In the present analysis, a comparative analysis of the basic assumptions and predictions of the classical and the generalized Gibbs approaches is given. It is shown, in particular, that—interpreted in terms of the generalized Gibbs approach—the critical cluster as determined via the classical Gibbs approach corresponds not to a saddle but to a ridge point of the appropriate thermodynamic potential hypersurface. By this reason, the classical Gibbs approach (involving the classical capillarity approximation) overestimates as a rule the work of critical cluster formation in nucleation theory and, in general, considerably.

FLUID CONDITION
Аннотация: The asymptotic behavior of the second B and third C virial coefficients in the low temperature region is analyzed for fluids with a spherical pair-additive potential of interparticle interaction. The temperature dependences B( T) and C( T) are approximated by expressions which convey correctly the behavior of the virial coefficients in the low-and high-temperature limits. The free parameters of approximation formulas for pure nitrogen, argon, and oxygen are determined. The derived virial equations of state are used to calculate the limit of significant instability of the gas phase in a wide temperature range.

Аннотация: The short-wave cutoff boundary of the capillary wave spectrum is established. Effective thickness L b of the “bare” density profile in the interfacial layer is calculated according to experimental data on the ellipticity ratio of reflected light. The free parameters of the extended van der Waals theory of capillarity are determined. The positions of the equimolecular dividing surface and tension surface are calculated, as well as the temperature dependence of the Tolman parameter.

VAN-DER-WAALS CHAIN-MOLECULE FLUID
Аннотация: An extended version of the Van der Waals capillarity theory is suggested, which describes the liquid-vapor interface in the temperature range from the triple to critical point. A model functional of thermodynamic potential of a two-phase Lennard-Jones system is suggested, which takes into account the impact of higher terms of gradient expansion. The identity of the thermodynamic and mechanical definitions of the Tolman parameter is proved within the accepted form of the functional. The properties of the liquid and vapor phase nuclei are described. The work of nucleation, the density profiles, and the dimensional dependence of surface tension are determined.

VAN-DER-WAALS CHAIN-MOLECULE FLUID
Аннотация: An extended version of the van der Waals capillarity theory describing the liguid-vapor interface in the temperature range from the triple to the critical point is suggested. A model functional of thermodynamic potential for a two-phase Lennard-Jones system taking into account the effect of the highest degree terms of gradient expansion has been constructed. The identity of the thermodynamic and the mechanical definition of Tolman’s length has been proved in the framework of the adopted form of functional. The properties of nuclei of the liquid and the vapor phase are described. The paper determines: the work of formation of a nucleus, density profiles, size dependences of the surface tension, and the parameter ? in the Gibbs-Tolman-Koenig-Buff equation.© 2004 American Institute of Physics.

    Space charge influence on the angle of conical spikes developing on a liquid-metal anode [Electronic resource] / G. Sh. Boltachev, N. M. Zubarev, O. V. Zubareva // Physical Review E: Statistical, Nonlinear, and Soft Matter Physics. - 2008. - Vol. 77, № 5-2. - P056607/1-056607/10

Аннотация: The influence of the space charge of ions emitted from the surface of a conical spike on its shape has been studied. The problem of the calculation of the spatial distributions of the electric field, ion velocity field, and the space charge density near the cone tip has been reduced to the analysis of a system of ordinary differential equations. As a result of numerical solution of these equations, the criterion for the balance of the capillary and electrostatic forces on the conic surface of a liquid-metal anode has been determined. It has allowed us to relate the electrical current flowing through the system, the applied potential difference, and the cone angle. We have compared the results of our calculations with available experimental data concerning emission from the surface of pure liquid gallium, indium, tin, and some liquid alloys, such as Au+Si, Co+Ge, and Au+Ge. On the basis of the proposed model, explanations have been given for a number of specific features of the emissive behavior of different systems.
