WebAbstract. Failure of tubes in shell and tube exchangers is attributed to flow induced vibrations of such tubes. There are different excitations mechanisms due to which flow induced vibration occurs and among such mechanisms, fluid elastic instability is the most prominent one as it causes the most violent vibrations and may lead to rapid tube … WebOct 1, 2024 · Flow-induced vibration is known to be caused by four mechanisms: turbulent buffeting, vortex shedding, fluid elastic instability (FEI), and acoustic resonance [1]. ... and studied the effect of single elastic tube and multiple elastic tubes on flow-induced vibration in a rigid tube array. The results showed that FEI is more likely to occur when ...
