ABSTRAKT

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.
