Process of intense erosion due to the surface collapse of air bubbles found in constricted rapid flows of water. Causes the detachment of material from a surface.

An implosion produced by locally low pressure, such as the collapse of a gas bubble in liquid (the energy of which is used as the source of seismic energy from air guns).

Inefficient low-pressure pockets on propellers form bubbles that collapse against the blades resulting in premature wear.

The phase changes that occur from pressure changes in a fluid that forms bubbles, resulting in noise or vibration in the water column. The Implosion of these bubbles against a solid surface, such as a hydraulic turbine, may cause erosion, and lead to reductions in capacity and efficiency pressure.

"formation of bubbles in fluid," 1895, from cavity + -ation. Earlier as a medical term (1868).

fast or even explosive erosion forced by air bubbles carried by a rapidly flowing liquid. Ruins its share of water pumps.

A localized low-pressure vaporization condition (cavities or bubbles) within a liquid, as around a propeller or within a pipe or in a pump’s suction line. Bubble collapse creates unwanted sound and/or [..]

formation of gas-filled cavities in liquids in motion when the pressure is reduced to a critical value. Low pressure regions are often created by rotating ship propellers. As the propellers rotate, bubbles form in the water. A loud acoustic sound is created when these bubbles collapse.

A physio-chemical process resulting in the production of microscopic explosions of gas within the brain following rapid acceleration of the brain inside the skull.

The formation and collapse of vapor- or gas-filled cavities that result from a sudden decrease and increase of pressure. Cavitation can cause mechanical damage to adjacent surfaces in meters, valves, pumps, and pipes at locations where flowing liquid encounters a restriction or change in direction.

inadequate lubrication caused by air taking place of oil in pump.

A localized gaseous condition within a liquid stream which occurs where the pressure is reduced to the vapor pressure.

The sudden formation and collapse of bubbles in liquids by means of mechanical forces creating low pressure.

Noise or vibration causing damage to the turbine blades as a results of bubbles that form in the water as it goes through the turbine which causes a loss in capacity, head loss, efficiency loss, and the cavity or bubble collapses when they pass into higher regions of pressure.

Vaporising of liquid that occurs at any point when the liquid’s pressure falls below its vapour pressure, or boiling point.

Cavitation refers to the formation and dispersal of gas bubbles in liquids under exposure to localised changes in pressure. It usually occurs in the vicinity of fast-moving objects in liquids, such as [..]

The formation of an air or vapour pocket (or bubble) due to lowering of pressure in a liquid, often as a result of a solid body, such as a piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the collapse of a vapour bubble. Cavitation can occur in a hydraulic system as a result of low fluid levels [..]

Air trapped around the propellor making it inefficient or at worst completely ineffective.

The formation of partial vacuum bubbles on submerged surfaces caused by low pressure arising from a hydrodynamic flow as a result of mechanical force, usually associated with the use of propellers. The collapse of the bubbles causes surface damage and pits.

The formation of bubbles on an aerofoil section in areas of reduced pressure. Can occur on heavily loaded ship propellers.

Loss of effective propeller thrust caused by the blades cutting across the column of water sucked along by the propeller instead of working in it. Can also lead to heavy vibration of the vessel.

Cavitation is the phenomenon of water vaporizing or boiling due to the extreme decrease in pressure on the forward, or, suction side of the propeller blade. Cavitation can be caused by nicks in the le [..]

Cavitation means that the centre of a tumour has died and a scan may show a hollowed out shell of cancer. This can be due to treatment or it may happen because the cancer grows faster than its blood supply.

a phenomenon in which the pressure within a liquid falls to a level low enough for the liquid to vaporise and form local cavities; this may occur in a propeller rotating in water causing a drop in propeller efficiency and pitting on blade surfaces
