Vapor Cavitation Zone Formation in a Water Layer

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 the layer. 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 coalescence. 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 splash it. The gas cavitation phenomenon and a de-aeration technology are also discussed.
