The role of wind deflector in wind turbines

The role of wind deflector in wind turbines

Installation of wind deflectors for flow augmentation helps to reduce the negative torque generated by the returning blades as well as enhance the positive torque by creating a diversion in the upstream wind towards the forwarding blade during operation. It was proven that using a suitable deflector system has the potential to improve wind turbine efficiency. The deflector acts as a directional headwind, increasing the local flow velocity to counter the resistance on one side of the rotor blades The average torque produced at an angle of 70 deg is 0.
