mass noun
  • 1Physics
    The formation of an empty space within a solid object or body.

    ‘One would expect elevated tritium levels only when deuterons are present and when sound waves produce cavitation, and that's what the Oak Ridge-RPI-RAS group found.’
    • ‘The role of branch junctions as a feature which enhances segmentation could also depend on the vulnerability to cavitation within the junction, but the present authors are unaware of any studies that have investigated this directly.’
    • ‘As a result of cavitation and embolism formation, stem hydraulic conductivity is reduced, which may be critical for a plant under drought stress.’
    • ‘The incidence of cavitation in pulmonary lung metastasis is approximately 4%.’
    • ‘The most common findings are isolated hilar or mediastinal adenopathy, segmental hyperinflation or atelectasis, alveolar consolidation, interstitial densities, pleural effusion or cavitation.’
    1. 1.1The formation of bubbles in a liquid, typically by the movement of a propeller through it.
      ‘The formation of such a bubble is called cavitation.’
      • ‘In liquid, these high-frequency waves cause the formation of microscopic bubbles, or cavitation.’
      • ‘Cavitation manifests itself in at least two modes; stable cavitation (slow, periodic oscillations of gas bubbles) and transient cavitation.’
      • ‘Sonoluminescence arises from acoustic cavitation - the formation, growth and implosion of small gas bubbles in a liquid blasted with sound waves above 18,000 cycles per second.’
      • ‘It may sound like a dental malady, but cavitation is a powerful natural force, a bombardment of microscopic bubbles that breaks down some of the hardest materials on earth.’
