In wind turbines, this type of blade design uses the direct impact of the wind to drive the turbine rotation. It is suitable for use in high wind speed environments. The blade contour is simple, with a small curvature, and mainly uses wind speed to achieve efficient energy conversion.
Vortex Generators (VGs) improve the performance of the blades by reducing flow separation. This leads to more torque turning the rotor and thus more energy produced. Even modern wind turbine blades suffer from a poor aerodynamic performance in the root region. The reasons are blade production and operational limitations.
A bionic dolphin blade triboelectric-electromagnetic hybrid generator (BDB-TEHG) enhances wind energy harvesting. The BDD-TEHG generates 0.712 mW of charging power at 2 m/s wind speed, 34 times more than a conventional wind turbine.
Pulsed blades mainly rely on the impact of high-speed airflow to transfer kinetic energy. In wind turbines, this type of blade design uses the direct impact of the wind to drive the turbine rotation. It is suitable for use in high wind speed environments.
