ABSTRACT
A model of the dynamics of vapor-bubble collapse in a channel, which takes into account hydraulic damping in a condensate flow, is developed. Numerical results are compared with experimental data. At a high rate of condensation, the numerical experiments show that high-frequency self-excited oscillations, such as the so-called "chugging" oscillations, could be obtained. Moreover, possible combinations of different types of self-excited oscillations which occur in condensation inside tubes are considered.
