Abstract

The paper deals with a model for the formation of a vapor bubble cavitation zone within a water layer due to a rarefied wave propagating in a drum boiler circulation circuit. The water in the layer is close to the saturation line (subheated). Models are presented for vapor cavitation zone development, pressure field formation and the phenomenon of swelling. The specific feature of the cavitation problem is the multiply reflected rarefied wave at the bottom and the formation of the most intensive cavitation zone near the bottom. The coalescing and floating bubbles can uplift the water layer and create an emergency situation in the control of the drum. The phenomenon is similar to the Kutateladze crisis for boiling liquid near a wall. The control system of the power station must take into account the danger of such uplifting.
