Three-Dimensional Numerical Analysis of Flow-Induced Vibration in Turbomachinery

The Connection between flow pattern evolution and vibration in 90‐degree pipeline: Bidirectional fluid‐structure interaction

“…In the past, scholars focused on axial flow and lateral flow-induced vibration research for specific industrial problems in various fields, which have far surpassed internal flow-induced vibration. [22][23][24][25] In recent years, more and more attention has been paid to the internal two-phase flow-induced vibration on pipeline components, [26][27][28][29] rotating components such as elbows suddenly change the flow direction, which leads to an increase in the probability of large amplitude vibration. 26,[30][31][32] The main frequency of pipeline vibration is mainly linearly related to the liquid superficial velocity, but is less related to the gas superficial velocity.…”
