Rapidly rotating objects in water - such as runners of rotary pumps, water turbines or ship propellers - create vapour bubbles due to rapid changes of pressure (cavitation).
These bubbles can implode when subject to higher pressure and generate intense shockwaves.
Cavitation can cause damage (as shown in the graphic), vibration and a loss of efficieny.
The graphic shows the damaged runner of a Francis-Turbine, which is often used in hydroelectric dams. The adjustable guide vanes or wicket gates of the turbine (yellow) regulate the water flow, depending on the water level of the reservoir.
