... generated on both sides of the structure, such as placing a cylinder in flow will cause the cylinder to VIV. When the oscillation frequency of the cylinder matches the frequency of the periodic wake vortex shedding (Khalak and Williamson, 1999), it will cause resonance, which is called the synchronization...
