cavitations

Cavitations is the plural of cavitation, a phenomenon where rapid changes in pressure cause the formation of small vapor-filled cavities in a liquid.

These bubbles collapse violently, which can damage machinery like boat propellers and pump impellers over time.

In medicine, cavitation refers to the formation of cavities in tissue, particularly in the lungs from diseases like tuberculosis.

The engineer noted cavitations were eroding the turbine blades.
