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 (FIV) occurs due to pressure pulsation in the flow that causes the pipe to vibrate. endstream endobj startxref By using our site, you agree to our collection of information through the use of cookies.
