... in-plane fluidelastic instability of tubes in the U-bend region of recirculating steam generators. In the tests, the damping ratios of a single steam generator tube vibrating parallel to a single pair of anti-vibration bars were measured using both a log-decrement and a power-based method. Non-contacting...

Paper No: PVP2019-94063
...Abstract Abstract The effect of the phase velocity models on the prediction of fluidelastic instability of a cantilever pipe subjected to gas-liquid internal flow is studied. According to the accepted fluidelastic formulation, a two-phase flow correlation is needed to relate phase velocities...

... The phenomenon of fluidelastic instability forms a major limitation on the performance of tube and shell heat exchangers. It is believed that fluidelastic instability is attributed to two main mechanisms; the first is called the “Damping Mechanism”, while the second is called the “Stiffness...
