Estimating the wake deflection downstream of a wind turbine in different atmospheric stabilities: an LES study [PDF]
Wind Energy Science, 2016 An intentional yaw misalignment of wind turbines is currently discussed as one possibility to increase the overall energy yield of wind farms. The idea behind this control is to decrease wake losses of downstream turbines by altering the wake ...

On the wake deflection of vertical axis wind turbines by pitched blades
Wind Energy, 2023 Wake losses are a critical consideration in wind farm design. The ability to steer and deform wakes can result in increased wind farm power density and reduced energy costs and can be used to optimize wind farm designs.

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.

An Analytical Model of Wake Deflection Due to Shear Flow [PDF]
, 2010 The main motivation behind this work is to create a purely analytical engineering model for wind turbine wake upward deflection due to shear flow, by developing a closed form solution of the velocity field due to an oblique vortex ring. The effectiveness of the model is evaluated by comparing the results with those of a free-wake model. The solution of
