High-frequency piping vibrations are called acoustic-induced vibration (AIV), because the flow is mostly gas and the vibrations typically produce sound waves within the range of human hearing. Flow-induced vibration comprises complex and diverse phenomena; subcritical vibration of nuclear fuel assemblies, galloping of transmission lines, flutter of pipes conveying fluid, and whirling of heat exchanger tube banks are typical examples.
