1/f noise and self-organized criticality in crisis regimes of heat and mass transfer / V. N. Skokov, V. P. Koverda, A. V. Reshetnikov, V. P. Skripov, N. A. Mazheiko, A. V. Vinogradov // International Journal of Heat and Mass Transfer. - 2003. - Vol. 46, № 10. - С. 1879-1883 Рубрики: ФИЗИКА Кл.слова (ненормированные): 1/f-NOISE -- FLUCTUATIONS -- FLICKER NOISE Аннотация: Thermal fluctuations under the transition from nucleate to film boiling of water on a wire heater and fluctuations of jet form during an outflow of superheated liquid from a pressure vessel were experimentally investigated. It has been found that power spectrum of the fluctuations has got a low frequency component corresponding to a 1/f law (flicker noise).??The effect given is connected with the occurrence of nonequilibrium phase transitions in the systems: a crisis of heat transfer under the transition from nucleate to film boiling and a crisis of a flow in boiling-up of superheated liquid jet?? |
