Аннотация: The critical temperatures and the critical pressures of aqueous solutions with mass fractions of hydrogen peroxide from 0 to 0.9 have been measured using the pulse-heating method applicable to thermally unstable substances. The critical temperature and the critical pressure of pure hydrogen peroxide have been determined by extrapolation. The results are compared with the values predicted by various methods

Аннотация: The results of the experimental investigations on the heat transfer of thin wires with water/oil and ether/water emulsions are given. The temperature of normal oil boiling is not lower than 340°C. A considerable delay in the crisis of bubble boiling is obtained for both emulsions, and is particularly noticeable for the ether/water emulsion. In the latter case the coefficient of connective heat transfer and the density of heat flux substantially exceed the corresponding values for pure initial liquids in the entire investigated range of temperatures (from 20 to 230°C) and pressures (from 0.1 to 3.6 MPa)

Аннотация: The critical temperatures and pressures of mono-, di-, tri-, and tetra-ethene glycols, and polyethene glycols with nominal molar massesM/M°(whereM°= 1 g·mol−1) equal to 300, 400, and 600, have been measured by the pulse-heating method applicable to thermally unstable substances. The results have been correlated as a function of the molar mass using the hole theory of liquids developed by Kurata and Isida with a slight modification

HELIUM
Аннотация: The method of lifetime measurement has been used to investigate the nucleation of the vapor phase in a superheated liquid nitrogen–helium solution. Temperature dependences of the mean lifetime of a metastable solution have been obtained in experiments at pressures p = 0.5, 1.0 MPa and several values of the mixture concentration. The nucleation rate J has been calculated. It varied in experiments from 104 tо 108 s?1 m?3. The results of experiments are compared with homogeneous nucleation theory. The paper deals with the size effect on the surface tension of a nucleus and the work of its formation.

ARGON
Аннотация: The kinetics of explosive boiling-up of liquid argon has been investigated at negative pressures created by the reflection of a compression pulse 3–5 µs long from the free surface of a liquid by the method of liquid pulse heating on a thin platinum wire (with a rate of temperature increase of about 1 K/µs). The limiting superheats T* (stretches p*), the effective nucleation rate J*, and the derivative GT=(d ln J/dT)T=T* have been determined by experimental data on the thermal perturbation of a wire probe and the results of solution of the problem on the initial stage of explosive boiling-up of a liquid. The experimental data are compared with homogeneous nucleation theory.

LIQUID
Аннотация: Molecular dynamics methods have been used to investigate the kinetics of the liquid-gas phase transition in a two-component Lennard-Jones system at negative pressures and elastic stretches of the liquid to values close to spinodal ones. The molecular dynamics system consists of 2048 interacting particles with parameters of the Lennard-Jones potential for argon and neon. Density dependences of pressure and internal energy have been calculated for stable and metastable states of the mixture at a temperature T*?0.7±0.01 and three values of the concentration. The location of mechanical and the diffusion spinodals has been determined. It has been established that a gas-saturated mixture retains its stability against finite variations of state variables up to stretches close to the values near the diffusion spinodal. The statistic laws of the process of destruction of the metastable state have been investigated. The lifetimes of the metastable phase have been determined. It is shown that owing to the small height of the potential barrier that separates the microheterogeneous from the homogeneous state a system of finite size has a possibility to make the reverse transition from the microheterogeneous into the homogeneous state. The lifetimes of the system in the microheterogeneous state, as well as the expectation times of the occurrence of a critical nucleus, are described by Poissonian distributions.

LENNARD-JONES FLUID
Аннотация: The method of molecular dynamics is used in a system of 2048 Lennard-Jones particles to determine the spinodal of a stretched liquid and crystal and the lines of their phase equilibrium at negative pressures. It is shown that a metastable extension of the melting line does not reach the zero isotherm, and ends on the spinodal of a stretched liquid. The point of termination of metastable liquid-crystal phase equilibrium is the singular point at a thermodynamic surface of states.

Аннотация: The critical pressures and the critical temperatures of ten tetraalkoxysilanes (tetraalkyl esters of silicic acid) Si[O(CH2)nH]4 with n = 1 to 10 have been measured. All the substances studied begin to decompose at temperatures below their critical points. The method of pulse-heating applicable to thermally unstable compounds has been used. Residence times were from (0.03 to 1) ms, which resulted in little decomposition of the substances during measuring. The experimental critical properties of tetraalkoxysilanes have been compared with the values estimated by the group-contribution methods of Lydersen and Nannoolal et al

Аннотация: The critical temperatures and critical pressures of six n-alkyl benzoates C6H5COO(CH2)nH with n = 1 to 6 have been measured. All the substances are thermally unstable at their critical points. The method of pulse-heating of a wire probe placed into the liquid under study has been used. Residence times are from (0.03 to 1) ms, which results in little decomposition of the liquid in the course of measuring. The experimental critical properties of alkylbenzoates have been compared with the values estimated by the group contribution methods of Constantinou and Gani and Marrero and Gani. ??
