Understanding the effects of rotation on the wake of a wind turbine at high Reynolds number
FlowThe wake of a horizontal-axis wind turbine was studied at a Reynolds number of $Re_D=4\times 10^6$ with the aim of revealing the effects of the tip speed ratio, $\lambda$ , on the wake.

Towards higher accuracy in wind farm deficit decay modelling – a comparison
Meteorologische Zeitschrift, 2023 Wind farm wake behaviour and forecasting is gaining the importance recently. It is especially relevant in the German Bight where space for wind farm clusters is limited, and wind farm wake lengths of up to 60 km have been measured.

POD analysis of the recovery process in wind turbine wakes
Journal of Physics: Conference Series, 2020 Abstract The wake produced by a single three-bladed wind turbine is investigated using the proper orthogonal decomposition (POD) of numerical data obtained by a large eddy simulation. The rotor blades are modeled using the actuator line method, whereas tower and nacelle are simulated through an immersed boundary method.

Convex Curvature Effect on the Wake Including Recovery from the Curvature
International Journal of Rotating Machinery, 1995 Streamwise convex-curvature effect including recovery process is discussed. Previous studies have demonstrated that even mild streamwise curvature has a marked effect on turbulence structure, heat transfer and skin friction coefficient.

Power curve and wake analyses of the Vestas multi-rotor demonstrator [PDF]
Wind Energy Science, 2019 Numerical simulations of the Vestas multi-rotor demonstrator (4R-V29) are compared with field measurements of power performance and remote sensing measurements of the wake deficit from a short-range WindScanner lidar system.
