The aerodynamics of the curled wake: a simplified model in view of flow control

Wind Energy Science, 2018
. When a wind turbine is yawed, the shape of the wake changes and a curled wake profile is generated. The curled wake has drawn a lot of interest because of its aerodynamic complexity and applicability to wind farm controls.
