RESUMO

The appearance of pressure oscillations in complete water vapor condensation inside a pipe, the outer surface of which is intensely cooled by cold water, is analyzed. The experiments with a model one-tube heat exchanger and industrial condenser are carried out. The existence of two modes of pressure oscillations is found. It has been established that the frequencies of these modes depend on an inclination of the channel to the horizon, heat flux density, presence of a noncondensed gas, and static pressure. The physical model of the occurrence of pressure oscillations has been developed. The qualitative agreement between the experiment and calculation is shown.
