How it works? | Vortex Bladeless

ENERGY HARNESS. When wind passes around a structure, vortexes of pressure are created. The frequency of vortexes depends on the wind speed, and if the structure has a similar natural resonating frequency, it begins to oscillate and harness their energy. This phenomenon of aeroelastic resonance is called Vortex Shedding, and happens regularly …

A state-of-the-art review of the vibration and noise of wind turbine ...

The vibration shortens the service life of drivetrain components. For example, the gearbox failures appear in advance in 2–11 years under poor working conditions [28] but the desired life is 20 years for gearboxes [29]. High vibration in wind turbines also decreases the efficiency of power generation [30].
