A New Streamwise Scaling for Wind Turbine Wake Modeling in the Atmospheric Boundary Layer
Energies, 2022 In this study, we aim to investigate if there is a scaling of the streamwise distance from a wind turbine that leads to a collapse of the mean wake velocity deficit under different ambient turbulence levels.

Multiple Wind Turbine Wakes Modeling Considering the Faster Wake Recovery in Overlapped Wakes [PDF]
Energies, 2019 In a wind farm some wind turbines may be affected by multiple upwind wakes. The commonly used approach in engineering to simulate the interaction effect of different wakes is to combine the single analytical wake model and the interaction model.
