Mitigation of vortex induced vibration through a new passive control

In this project, we develop an innovative flow control technique to reduce the flow-induced noise and vibration on a lifting surface. This device, which can be attached to the trailing edge of a blade, may prevent from the formation of coherent and strong vortex structures in the wake flow. It can greatly reduce the vibration and noise and prevents from flutter occurrence. It may be beneficial in a wide range of applications, such as hydro turbines and pumps, marine propellers, wind turbines, airplanes, lifting foils for high-speed boats.
