THERMODYNAMIC PROPERTIES -- CRYSTAL -- LIQUID -- GAS
Аннотация: The thermodynamic properties of crystal, liquid, and gas in the stable and metastable states have been determined by molecular dynamics simulation of a system of 2048 Lennard-Jones particles. The spinodals of a superheated crystal, a superheated liquid, and a supersaturated vapor have been approximated; the spinodal for a supercooled liquid turns out to be nonexistent. The liquid-vapor, liquid-crystal, and crystal-vapor equilibrium curves and their extensions beyond the triple point have been calculated. It has been shown that, as distinct from the metastable extension of the saturation curve, which terminates at the zero isotherm, the metastable melting and sublimation curves terminate at, respectively, the stretched liquid and superheated crystal spinodals. The properties of the critical end points of metastable equilibrium of extended phases are considered

METHOD MOLECULAR DYNAMICS -- INTERNAL ENERGY -- LENNARD-JONES
Аннотация: A method of molecular dynamics is used to calculate the pressure, internal energy, and isochoric heat capacity in a system of 2048 Lennard-Jones particles in the range of reduced temperatures from 0.1 to 2.0 and the range of densities from 0.001 to 1.15. Local equations of state for the gas, liquid, and crystalline phases are derived. The spinodals of a superheated (extended) liquid, supersaturated vapor, and superheated (extended) crystal are determined. It is shown that the spinodal of a supercooled liquid is nonexistent. An algorithm to calculate the lines of phase equilibria is constructed. The lines of liquid-gas, liquid-crystal, crystal-gas phase equilibria, and their metastable extensions are determined. It is shown that the metastable extensions of the melting and sublimation lines terminate at the spinodals of the liquid and crystal, respectively. The properties of final critical points in the lines of melting and sublimation are considered

    The self-diffusion coefficient in metastable states of a Lennard-Jones fluid / V. G. Baidakov, Z. R. Kozlova // Chemical Physics Letters. - 2010. - Vol.500, №1-3. - С. 23-27

MOLECULAR-DYNAMICS SIMULATION -- CRITICAL POINTS -- VISCOSITY
Аннотация: Molecular-dynamics computer simulation has been used to calculate the self-diffusion coefficient of a Lennard-Jones fluid in the interval of reduced temperatures T* = 0.35-2.0, through mean-squared particles displacements and the velocity autocorrelation function. Calculations have been performed for systems in stable and metastable states up to the boundary of spontaneous nucleation in a model of a fluid consisting of 2048 particles. The values of the self-diffusion coefficient on the spinodals of a superheated liquid and supersaturated vapor have been determined. It has been established that in the region of supercooled states of the liquid phase on an isotherm the logarithm of the self-diffusion coefficient is a linear function of the pressure

EQUATION OF STATE -- COMPUTER SIMULATION -- LENNARD-JONES FLUID -- METASTABLE PHASES -- SPINODALS
Аннотация: The method of molecular dynamics has been used to calculate the pressure, internal energy and isochoric heat capacity of the Lennard–Jones fluid for 208 states in the range of temperatures 0.35 kBT 2.0 and densities 0.001 1.2. The array of data obtained, along with stable states, includes homogeneous metastable states (supersaturated vapor, superheated and supercooled liquid). Spinodals of supersaturated vapor and superheated liquid have been approximated. In a stable region the data obtained are compared with the results of previous papers. The behavior of thermodynamic properties of the fluid in the event of homogeneity disturbance and formation of micro-heterogeneous (“two-phase”) states has been considered.
