Stochastic resonance in the crisis boiling regime under periodic heat release

详细

The results from experimental study of thermal pulsations on going from the nucleate to film boiling of water on a wire heater with a periodic Joule heat release are given. The intermittency between the nucleate and film boiling regimes was observed at a frequency of the periodic current component of less than 0.1 Hz. In this case, the amplitude of thermal pulsations increased about fourfold. The data obtained are interpreted as a stochastic resonant response of the system when the periodic component of pulsations increases in the presence of noise.
