Fluid-structure interactions are widely seen in engineering. For example, when flow blows over a slender structure (off-shore structures, high-rise buildings, cable-stayed bridges, and fluid machinery, etc.), vortices separate alternately from the structure, giving rise to excitation forces and causing the structure to vibrate. The structural motion in turn influences the flow field, resulting in a highly nonlinear fluid-structure coupling. This type of fluid-structure interaction may affect the fatigue life of engineering structures and even lead to structural damages and serious accidents, and has become one of the major concern in many applications. Furthermore, vortex shedding is responsible for noise generation in case the kinetic energies of vortical motions are converted into the acoustic wave involving the longitudinal oscillation of fluid particles. Therefore, the control of flow and its induced structural vibration has attracted the interests of many researchers for many years. A novel surface perturbation technique has been developed recently and applied to control fluid-structure interactions, including vortex streets, flow-induced vibrations and vortex-induced noise. In this article, we summarize this technique, major applications, control performances, and possible physical mechanisms responsible for flow modification, drag reduction, controlling fluctuating forces/structural vibrations, and noise control.
