摘要:

Equilibrium molecular dynamics computer simulations have been used to determine the transport coefficients of model Ar—Kr mixtures, which are represented by Lennard-Jones pair potentials with Lorentz—Berthelot rules for the cross-species interactions. The component self-diffusion and mutual-diffusion coefficients are calculated from time correlation functions and mean square displacements. Time correlation functions are used to evaluate the shear and bulk viscosity, thermal conductivity and the thermal diffusion coefficient (Soret/Dufour coefficient). In the case of the thermal transport coefficients, the partial enthalpy of the two species is required at each state point to define the heat flux rigorously. We obtain this and the partial volume (and species resolved chemical potential) using particle-exchange (and particle insertion) techniques implemented in separate [NPT] simulations at the same state point.

摘要:

A simple equation of state for the condensed phase, proposed by Cho, is applied to liquid water under pressure up to 8000 bar and between 25 and 150°C. The agreement between measured and calculated volumes is satisfactory over the entire range of temperatures and pressures. The equation shows that the abnormalities in the temperature and pressure dependence of the thermal expansivity, isothermal compressibility and the heat capacity are predicted quite accurately from PVT data only. The values of thermal expansivity, isothermal compressibility, and heat capacity at constant pressure are calculated, and detailed comparisons with the experimental values are made.

摘要:

In this work, new definitions of the normalized temperature and surface tension are proposed which result in a single plot for the surface tension of molten alkali metals. The functional dependence of the reduced surface tension on the reduced temperature can be adequately described by a straight line; the intercept and slope have been obtained using the linear regression approach. The method proposed herein predicts the values of surface tension at various temperatures with an average error of about 5%.

摘要:

Viscosity coefficients and densities of binary mixtures of 2,2,2-trifluoroethanol with aniline andN-alkylanilines have been measured at five temperatures over the entire composition range. From the experimental data, excess volumes, viscosities and free energies of activation values were calculated and discussed in terms of intermolecular interactions between the components in the binary mixtures. Semiempirical equations of McAllister and Heric were employed to fit the experimental viscosity of the binary mixtures.
