Заглавие : Boiling up of jets of superheated ethanol-water solutions Место публикации : Journal of Engineering Thermophysics. - 2007. - Vol.16, №4. - С. 244-248 ББК : 53 Предметные рубрики: ФИЗИКА Ключевые слова (''Своб.индексиров.''): evolution of the shapes --superheated aqueous solutions --low-boiling liquid Аннотация: The stability and evolution of the shapes of jets of strongly superheated aqueous solutions of ethanol flowing out of a high-pressure chamber are experimentally investigated at various initial parameters. It has been found that a low-boiling liquid causes shifting to lower temperatures of the boundaries between various kinds of boiling-up jets, such as cylindrical, conical, and open. Large-scale pulsations of the jet shapes are observed in the temperature range from 454 to 484 K, where the jet completely breaks down. The conditions for the formation of large-scale low-frequency pulsations with a power spectrum diverging inversely proportional to the frequency f (1/f spectra) have been revealed. Such fluctuations prove that the flow is unstable and large-scale low-frequency ejections are possible Доп.точки доступа: Reshetnikov, A. V.; Vinogradov, A. V.; Begletsov, V. N. ; Skokov, V.
