Riso National Laboratory and the Technical University of Denmark examine the aerodynamic influence of winglets

Winglets are curved extensions of wind turbine blades which increase power production without increasing the area swept by the blades, thus making them suitable for wind farms and sites restricting rotor diameter. Since they are more expensive to produce, design for optimal efficiency is necessary.

Using Vortex Lattice simulations as well as faster, simpler numerical modeling, this study from Riso National Laboratory and the Technical University of Denmark examines the aerodynamic influence of winglets on turbine blades in order to predict their performance.
