Acoustic noise of a boiling liquid

This paper presents ideas on the mechanism of the emission of noise for different regimes of convective liquid boiling. Based on the analysis of experimental data, fundamental differences in the amplitude-frequency spectra of the acoustic noise accompanying these regimes are revealed as well as the nature of elementary sound emitters in a boiling liquid. Methods are indicated which allow one in principle to diagnose the regime of boiling in large reservoirs or cylindrical channels.
