Study on Complex Wake Characteristics of Yawed Wind Turbine Using Actuator Line Method
Journal of Marine Science and Engineering, 2023 In modern large-scale wind farms, power loss caused by the wake effect is more than 30%, and active yaw control can greatly reduce the influence of the wake effect by deflecting the wind turbine’s wake.

The characteristics of helically deflected wind turbine wakes
Journal of Fluid Mechanics, 2023 The helix approach is a new individual pitch control method to mitigate wake effects of wind turbines. Its name is derived from the helical shape of the wake caused by a rotating radial force exerted by the turbine. While its potential to increase power production has been shown in previous studies, the physics of the helical wake are not well ...

Control-oriented model for secondary effects of wake steering [PDF]
Wind Energy Science, 2021 This paper presents a model to incorporate the secondary effects of wake steering in large arrays of turbines. Previous models have focused on the aerodynamic interaction of wake steering between two turbines. The model proposed in this paper builds on

Lidar measurements of yawed-wind-turbine wakes: characterization and validation of analytical models [PDF]
Wind Energy Science, 2020 Wake measurements of a scanning Doppler lidar mounted on the nacelle of a full-scale wind turbine during a wake-steering experiment were used for the characterization of the wake flow, the evaluation of the wake-steering set-up, and the validation of ...

Experimental study of the wake interaction between two vertical axis wind turbines
Wind Energy, 2023 Wakes and wake interactions in wind turbine arrays diminish energy output and raise the risk of structural fatigue; hence, comprehending the features of rotor–wake interactions is of practical relevance.

Changing the rotational direction of a wind turbine under veering inflow: a parameter study [PDF]
Wind Energy Science, 2020 All current-day wind-turbine blades rotate in clockwise direction as seen from an upstream perspective. The choice of the rotational direction impacts the wake if the wind profile changes direction with height.

Modeling lateral plume deflection in the wake of an elongated building
Atmospheric Environment, 2020 The plume dispersion model AERMOD provides an efficient method for modeling ground-level pollutant concentrations in wakes of buildings. In recent years, several studies have shown that the downwash algorithms within AERMOD often perform poorly in certain applications.
