Stoichastic resonance in the crisis boiling regime under periodic heat release

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.
