Cavitation in fluid mechanics and engineering normally is the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapor pressure, leading to the formation of small vapor-filled cavities in the liquid. [1]

2021年8月25日 · Cavitation is a condition that can affect any fluid flow system. Despite it being an ever-present threat, it is not well understood. In the simplest possible terms, cavitation involves the formation of water vapor bubbles that damage metal components when they collapse back to the liquid phase.

5 天之前 · cavitation, formation of vapour bubbles within a liquid at low-pressure regions that occur in places where the liquid has been accelerated to high velocities, as in the operation of centrifugal pumps, water turbines, and marine propellers.

Cavitation begins when the local pressure falls far enough below the saturated vapour pressure, which is determined by the liquid's tensile strength at a given temperature.

It is a low-pressure phenomenon. If the pressure of the flowing fluid at any point in the fluid flow becomes less than the saturated vapour pressure at constant temperature then the cavitation occurs. In cavitation, cavities of vapours in liquid or bubbles are formed.

Cavitation occurs in fluid flow systems where the local static pressures are below the fluids vapor pressure. Cavitation is a common problem in pumps and control valves - causing serious wear, tear and damage. Under the wrong conditions cavitation reduces components life time dramatically. What is Cavitation?

The definition of cavitation is given as a two-stage process associated with the flow of liquids. The first stage involves the formation of vapour cavities or bubbles in the flow stream as a result of the local static pressure in the flow stream dropping below the liquid vapour pressure.

Cavitation is a phenomenon characterized by the formation and rapid collapse of vapor-filled cavities within a liquid. These cavities, often referred to as bubbles, appear when the local pressure of the fluid drops below its vapor pressure.

The phenomenon of cavitation consists in the disruption of continuity in the liquid where there is considerable local reduction of pressure. By understanding the cavitation mechanisms, we can detect and prevent the phenomenon before failure occurs.

What is cavitation? Cavitation is the phenomenon of formation of a vapour bubble in flowing liquid where the pressure falls below vapour pressure and sudden collapsing of this bubble at high-pressure region.
