Flow Induced Vibration

The shedding alternates at regular time intervals and therefore produces an oscillating pressure field pulsation.  The pulsation can then drive vibration of the obstruction and/or other components of the system.  Some common types of problems associated with flow induced vibration (FIV) are:

  • Strainer Failures
  • Large Duct Vibration
  • Cooler Tube Vibration
  • Pressure Relief Valve Vibration

Field tests in conjunction with calculations are generally required to identify the obstruction which is producing the vortices.  Pulsation and vibration measurements are essential to obtain solutions to vibration problems caused by FIV.
