Multi-frequency cavitation vessel being used for a reference experiment. Cavitation is the formation and rapid collapse of bubbles in a liquid due to changes in pressure. This vessel uses different acoustic frequencies to produce the changes in pressure that cause cavitation. Cavitation is an important consideration in engineering, where it can cause wear and tear on and in structures such as pumps and propellers. It can also be used in cleaning processes.
