Cavitation is usually an undesirable occurrence. In devices such as propellers and pumps, cavitation causes a great deal of noise, damage to components, vibrations, and a loss of efficiency. Noise caused by cavitation can be particularly undesirable in naval vessels where such noise may render them more easily detectable by passive sonar. Cavitation has also become a conce… WebCavitation occurs when the pressure in the cylinder drops below atmospheric pressure, so gasses trapped in the oil expand rapidly. Cavitation can damage the cylinder, pitting …
