... cylinder. A typical phenomenon observed in the VIV of a circular cylinder is lock-in, characterized by the synchronization of vortex shedding frequency which synchronizes with the frequency of body oscillation (Williamson and Govardhan, 2004). Comprehensive investigations have been carried out in various...
