An experimental study on the effects of winglets on the tip vortex interaction in the near wake of a model wind turbine

Bartl, Jan; Mühle, Franz Volker; Hansen, Thomas; Adaramola, Muyiwa S.; Sætran, Lars Roar (Journal article; Peer reviewed, 2020)

An experimental study of the near wake up to four rotor diameters behind a model wind turbine rotor with two different wing tip configurations is performed. A straight-cut wing tip and a downstream-facing winglet shape are ...
Vortex interaction in the wake of a two- and three-bladed wind turbine

Bartl, Jan Michael Simon; Hansen, Thomas; Kuhn, Wolf Ludwig; Mühle, Franz Volker; Sætran, Lars Roar (Journal article; Peer reviewed, 2020)

The vortex interaction in the wake behind a two- and three-bladed model scale wind turbine is investigated. The two rotors have equal solidity, and produce similar power and thrust at the design tip speed ratio. Phase-averaged ...
