Flow-induced vibration of a flexible cantilever in tandem configuration

This study explores the fluid-structure interaction of a flexible cylindrical cantilever in a tandem configuration, focusing on sustained oscillations across subcritical and post-critical Reynolds number regimes. A fully coupled numerical solver is used to analyze spatiotemporal power transfer patterns, response amplitudes, and vorticity dynamics. The findings reveal that wake-body interactions and vortex synchronization drive sustained oscillations, offering insights into the design of bio-inspired cantilever flow sensors.
