Cavitation (Boating)

Essentially, to suck air. This term is primarily used in conjunction with propellers and rudders. When cavitating, the propeller will speed up, but power is lost; the rudder may lose steering action. Cavitation most often occurs when turning. Both result from a loss of a constant solid water flow. Power catamarans usually require deflectors when a single motor is used, to direct a flow of water to the propeller. Webster's Dictionary: "the formation of partial vaccums in a flowing liquid as a result of a separation of its parts". i.e. aeration of the liquid.

Cavitation (Car Care)

Formation of a n air or vapor bubble due to lowering of pressure in a liquid, often as a result of a solid body, such as a propeller or piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the collapse of a vapor bubble. Cavitation can occur in a hydraulic system as a result of low fluid levels that draw air into the system, producing tiny bubbles that expand explosively at the pump outlet, causing metal erosion and eventual pump destruction.

Cavitation (Carpet)

The formation of partial vacuums in a fluid, caused by high frequency sound waves.

Cavitation (Corrosion)

The formation and instantaneous collapse of innumerable tiny voids or cavities within a liquid subjected to rapid and intense pressure changes. Cavitation produced by ultrasonic radiation is sometimes used to effect violent localized agitation. Cavitation caused by severe turbulent flow often leads to cavitation damage

Cavitation (Environment)

The formation and collapse of gas pockets or bubbles on the blade of an impeller or the gate of a valve; collapse of these pockets or bubbles drives water with such force that it can cause pitting of the gate or valve surface.

Cavitation (Import Cars)

The presence of air in a liquid during pumping, which can inhibit the flow of the liquid.

Cavitation (Metal)

The formation and instantaneous collapse of innumerable tiny voids or cavities within a liquid subjected to rapid and intense pressure changes. Cavitation produced by ultrasonic radiation is sometimes used to give violent localized agitation. That caused by severe turbulent flow often leads to cavitation damage.

Cavitation (Physical Geography)

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.

Cavitation (Plumbing)

The vacuum created when the discharge capacity of the pump exceeds the replacement in the suction line. This causes bubbling and vibrations that can damage the pump if they occur over an extended period.

Cavitation (Sanitation)

(1) The formation and collapse of a vapor pocket or bubble on the blade of an impeller due to the internal pressure dropping below the atmospheric pressure of the liquid being pumped. The collapse causes water to be driven into the surface of the impeller with such force that pitting of the impeller surface may occur. (2) The formation of a cavity between the downstream surface of a moving body, for example, the blade of a propeller and a liquid normally in contact with it. (3) Describing the action of an operating centrifugal pump when it is attempting to discharge more water than suction can provide.
