BOILING-UP LIQUID -- CRITICAL MODES -- VAPOR FORMATION
Аннотация: Change of the shape of a boiling-up liquid jet flowing from a high-pressure vessel at high superheatings was investigated experimentally. Mechanisms of volumetric heterogeneous and homogeneous nucleation are distinguished and their connection with critical modes of outflow is determined. Results of the experimental study of recoil of boiling-up liquid jets in a thermodynamically strong nonequilibrium mode of outflow are presented. The dynamics of vapor content fluctuations is studied by a method of photometry of passed laser radiation. Fluctuations of pressure in a superheated liquid jet at various mechanisms of vapor formation are measured by a method of strain metering. It was found that in intense volumetric boiling-up of a superheated liquid jet the power spectrum of fluctuations has a low-frequency component (flicker-noise) which diverges according to the 1/f law. This effect is related to nonequilibrium phase transitions in the system

Аннотация: A binary Van-der-Waals solution is considered. Within the framework of the Gibbs and Van-der-Waals capillary theories under the conditions of constancy of the temperature and the composition the sise dependences of surface tension s(R) are calculated for critical nuclei of liquid and vapor. The phenomenon of "closure" of size dependences s(R) and the presence anomalously of high maximums on them are established

Kinetic aspect of the life of tensile specimens: A comparison of two approaches [Текст] / V. P. Skripov, V. E. Vinogradov // Journal of Applied Mechanics and Technical Physics. - 2005. - Vol. 46, № 5. - С. 697-701

KINETICS ASPECTS
Аннотация: This paper considers two approaches to estimating the life of specimens: kinetic strength theory and homogeneous nucleation theory. Using aluminum as an example, it is shown that homogeneous nucleation theory overestimates the real life of tensile metal specimens by two order of magnitude and gives values close to the theoretical strength of metals. The use of experimental data on the lifetime of a superheated and stretched liquid (hexane) allows one to couple both approaches taking into account the time scale of occurrence of metastability.

Аннотация: Crystallization of supercooled liquid sodium containing a spheroidal bce nucleus was studied by molecular dynamics simulations. The degree of supercooling and the critical nucleus size are determined. After solidification, the system exhibits elasticity of shear. Nucleus growth is accompanied by self-sustained aperiodic temperature oscillations. The radial distribution function is computed and Voronoi polyhedra are constructed for the system immediately before and after the transition. It is shown by the projection method that the crystallized system contains structural defects and Features a long-range order
