WebA mathematical model for flow-induced vibrations in heat exchanger tube banks is presented which includes the effects of vortex shedding, fluidelastic coupling, drag force, and fluid inertia coupling. Once the fluid forces are known, the model can predict the details of complex tube-fluid interactions: (1) natural frequencies and mode shapes of ... WebFlow-induced vibration (FIV) can be characterized by 4 different excitation mechanisms including fluid elastic instability (FEI), vortex shedding, turbulent buffeting, and acoustic resonance. Turbulent buffeting and vortex shedding may cause a slight damage in tube bundles due to flow-induced vibrations over an extended amount of time or they how to solve spill error in vlookup
