Analysis of interface oscillations during boiling
Résumé
This paper presents experimental data and simulation of the interface oscillations at bubble growth during pool nucleate boiling. It is shown that during the bubble growth on heat transfer surface, oscillations of the bubble volume take place, as well as oscillations of the bubble shape. Spectra of acoustic and optical sensors signals are obtained, that show an existence of correlation between interface oscillations and pressure oscillations in liquid during pool nucleate boiling. Several results of simulation of the oscillation process are also presented. Bubble - radius changes in time obtained using this model correspond to new experimental data. For the first
time, attractors for the system under simulation are obtained.
