Abstract
The periodic wake flow past a bluff body immersed in a moving fluid can be synchronized to the harmonic vibrations of the body. A low-dimensional, phase-based analysis has been adopted to uncover the theoretical conditions necessary for synchronization between the wake and body oscillations. The present phase-based methodology allows for modifying the transient features of unsteady flows, thereby enabling the online control and analysis of aerodynamic forces on flyers/swimmers, vortex-induced vibrations, and fluid-structure interactions.
