Investigation of wind turbine flow and wake

open access: yesJournal of Fluid Science and Technology, 2014
This paper is dedicated to the investigation and analysis of wind turbine wake. An experimental work is undertaken in wind tunnel on a horizontal axis wind turbine model. The velocity field in the wake is measured using PIV with phase synchronization in order to relate velocity and vortices to the rotating blades.

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

open access: yesWind Energy
When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices.
