(earth science) erosion of rocks caused by the forcing of air into cracks. Cavitation results from the pounding of waves on the coast and the swirling of turbulent river currents, and exerts great pressure, eventually causing rocks to break apart.
The process is particularly common at waterfalls, where the turbulent falling water contains many air bubbles, which burst to send shock waves into the rocks of the river bed and banks.
Formation of partial vacuums in fluids at high velocities, produced by propellers or other machine parts in hydraulic engines, in accordance with Bernoulli's principle. When these vacuums collapse, pitting, vibration, and noise can occur in the metal parts in contact with the fluids.
The boiling of a liquid caused by a decrease in pressure rather than an increase in temperature. + prikaži više
