Wind Farm Loads under Wake Redirection Control
Energies, 2020 Active wake control (AWC) is a strategy for operating wind farms in such a way as to reduce the wake effects on the wind turbines, potentially increasing the overall power production. There are two concepts to AWC: induction control and wake redirection.

Wind-Turbine Wakes in a Convective Boundary Layer: A Wind-Tunnel Study [PDF]
, 2018 Thermal stability changes the properties of the turbulent atmospheric boundary layer, and in turn affects the behaviour of wind-turbine wakes. To better understand the effects of thermal stability on the wind-turbine wake structure, wind-tunnel ...

International Journal of Renewable Energy Development, 2022 The objective of this paper is to investigate the ability of analytical wake models to estimate the wake effects between wind turbines (WTs). The interaction of multiple wakes reduces the total power output produced by a large offshore wind farm (LOFWF).

Simulating wind turbine interactions using the vorticity transport equations [PDF]
, 2009 The aerodynamic interactions that can occur within a wind farm result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Wake Statistics of Different-Scale Wind Turbines under Turbulent Boundary Layer Inflow
Energies, 2020 Subscale wind turbines can be installed in the field for the development of wind technologies, for which the blade aerodynamics can be designed in a way similar to that of a full-scale wind turbine. However, it is not clear whether the wake of a subscale
