Abstract:
In the operation of water cooled nuclear reactor and other heat exchange installations have importance predict a heat transfer crisis and boiling onset. The paper presents a method for predicting changes in heat transfer regimes in power energy equipment. The technique is based on the amplitude-frequency analysis of temperature fluctuations of the heater surface. It was found experimentally that in the region of heat transfer regime change (from convective to nucleate boiling or from nucleate boiling to film boiling) the fluctuation spectrum is close to flicker noise.
