Ключевые слова (''Своб.индексиров.''): molecular-dynamics simulation--liquid-vapor interface--lennard-jones fluid
Аннотация: We present the molecular dynamic simulation results for the liquid–vapour interface of the pure Lennard–Jones fluid. The thermodynamical properties, the surface tension, the effective thickness of interfacial layer and the mean-square amplitude of capillary waves are determined. Calculations have been performed at cut-off radii of the intermolecular potential rc1=2.6σ and rc2=6.78σ. It is shown that the cut-off radius of the interaction potential in the two-phase systems should be chosen to be larger than that in the one-phase systems for an adequate representation of properties

ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): liquid cryogenic--state metastable--state superheated--dependence of temperature--nucleation--p-properties--rho-properties--t-properties--ultrasound velocity
Аннотация: The results of an experimental investigation of cryogenic liquids in a metastable (superheated) state are considered. Data are presented on the maximum attainable superheat temperature of typical cryogenic liquids from atmospheric to close to critical pressures. The nucleation mechanism and the influence of factors that induce boiling on the attainable superheat of liquids are discussed. The results of experiments are compared with theory. Data on the thermodynamic properties (P, rho, T properties, heat capacity, ultrasonic velocity and attenuation, volume viscosity) of cryogenic liquids in a metastable liquids is discussed. Explosive boiling phenomena connected with large superheats of cryogenic liquids are considered, and the discharge of cryogenic liquids through short tubes and the heat interaction of cold liquid droplets with a hot surface are investigated

Заглавие : First-order curvature corrections to the surface tension of multicomponent systems
Место публикации : Journal of Colloid and Interface Sience. - 2003. - Vol.264, №1. - С. 228-236
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): surface tension--phase coexistence--multicomponent systems
Аннотация: The dependence of surface tension on curvature is investigated for the case of an equilibrium phase coexistence in multicomponent systems. Employing Gibbs's method of description of heterogeneous systems, an equation is derived to determine the dependence of surface tension on curvature for widely arbitrary paths of variation of the independent thermodynamic parameters. It is supposed hereby merely that the temperature is kept constant and that the variations of the different molar fractions are such that the radius of the dividing surface varies monotonically in dependence on the change of the state parameters of the ambient phase along any of the chosen paths. In the analysis, an approach developed by Blokhuis and Bedeaux for one-component systems is utilized. It relies on the expansion of the surface free energy on curvature of the dividing surface. An equation is derived that connects the first-order correction term in the expansion with the interaction potential of the particles in the multicomponent solution and with the two-particle distribution functions in the planar interfacial layer between the two phases coexisting in equilibrium at planar interfaces. The connection of the first-order curvature correction to the surface tension and the first moment of the pressure tensor at a planar interface is analyzed as well

Заглавие : The Second and Third Virial Coefficients of Simple Fluids
Место публикации : High Temperature. - 2006. - Vol. 44, № 1. - С. 83-90
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): 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.

Заглавие : Gyroscopic Effect in Low-Energy Classical Capture of a Rotating Quadrupolar Diatom by an Ion
Место публикации : Journal of Physical Chemistry A. - 2006. - Vol. 110, № 9. - С. 2876-2884
ББК : 53
Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): gyroscopic effect
Аннотация: The low-energy capture of homonuclear diatoms by ions is due mainly to the long-range part of the interpartner potential with leading terms that correspond to charge?quadrupole interaction and charge-induced dipole interaction. The capture dynamics is described by the perturbed-rotor adiabatic potentials and the Coriolis interaction between manifold of states that belong to a given value of the intrinsic angular momentum. When the latter is large enough, it can noticeably affect the capture cross section calculated in the adiabatic channel approximation due to the gyroscopic property of a rotating diatom. This paper presents the low-energy (low-temperature) state-selected partial and mean capture cross sections (rate coefficients) for the charge?quadrupole interaction that include the gyroscopic effect (decoupling of intrinsic angular momentum from the collision axis), quantum correction for the diatom rotation, and the correction for the charge-induced dipole interaction. These results complement recent studies on the gyroscopic effect in the quantum regime of diatom?ion capture

Ключевые слова (''Своб.индексиров.''): flexible molecules--ir spectrum--molecular dynamics
Аннотация: Abstract-Interaction of bromine ions with water clusters that have absorbed the molecules of oxygen and ozone is studied using a molecular-dynamics simulation of flexible molecules. The cases of location of Br-ions on the surface and in the bulk of the cluster are described. Water clusters with ozone molecules remain stable during their interaction with the Br - ions, while oxygen molecules are found to evaporate from the cluster when Br - ions appear in its bulk. In the presence of Br - ions, the infrared spectra of systems with O 3 molecules are observed to be intensified. The intensities of the IR spectra with O 2 molecules may both increase and decrease depending on the arrangement of the Br - ions. The Raman spectra are sensitive to the appearance of Br - ions only for systems that contain oxygen molecules. As a result of interaction with the Br-ions, the power of IR radiation emitted by the clusters can not only increase, but also decrease

Предметные рубрики: ФИЗИКА
Ключевые слова (''Своб.индексиров.''): bromine ions --infrared and raman spectra--water clusters
Аннотация: The interaction of (Br -) iH 2O) 50-i, 0 ≤ i ≤ 6 clusters with oxygen and ozone molecules is investigated by the method of molecular dynamics simulation. The ozone molecules as well as the bromine ions do not leave the cluster during the calculation of 25 ps. The ability of the cluster containing molecular oxygen to absorb the infrared (IR) radiation is reduced in the frequency range of 0 ≤ ω ≤ 3500 cm -1 when the number of the bromine ions in the cluster grows. The intensity of the Raman spectrum is not changed significantly when the Br - ions are added to the ozone-containing system. The power of the emitted IR radiation is increased when the number of bromine ions grows in the oxygen-containing system. The data obtained in this study on the IR and the Raman spectra of the water clusters that contain ozone, oxygen, and Br - can be used to develop an investigation of the mechanisms of ozone depletion

Аннотация: The interaction of ozone molecules with water clusters at a temperature corresponding to the middle zones of the troposphere and the stratosphere has been studied by the molecular-dynamics method. It has been established that the integral intensities of the infrared absorption spectrum and the Raman spectrum of an ultradisperse aqueous system decrease substantially in absorption of ozone by it. It has been shown that in this case the emission power of the IR-radiation energy stored by the entire ozonized disperse aqueous medium grows
