Dictionary:Cavitation

{{#category_index:C|cavitation}} (kav, i tā’ sh∂n) The formation and collapse of cavities (bubbles) in a fluid caused by the static pressure becoming smaller than the fluid vapor pressure. The collapse generates a shock wave by implosion. The outward momentum of water and gases from an underwater explosion (and other marine energy sources) usually produces such a low-pressure region, the collapse of which produces a bubble effect.
