Enhancement of SAR Ship Wake Image Based on FABEMD and Goldstein Filter

open access: yesLeida xuebao, 2012
Enhanced SAR ship wake images with blur Kelvin wakes and reserved turbulent wakes are very important to the inversions of ship and motion parameters.

Effects of wind turbine wakes on microclimate properties near the ground

open access: yes, 2021
Archer, Cristina L.Wind energy has been growing steadily in the U.S. and worldwide in the past decades. As wind farms are projected to increase in size and number, however, concerns are rising about possible undesirable effects of wind turbines near the ...

Investigation of the floating IEA Wind 15 MW RWT using vortex methods Part I: Flow regimes and wake recovery

open access: yesWind Energy, 2022
Floating wind turbines have the potential to enable global exploitation of offshore wind energy, but there is a need to further understand the complex aerodynamic phenomena they can encounter due to floater induced rotor motion.

Long-range modifications of the wind field by offshore wind parks – results of the project WIPAFF

open access: yesMeteorologische Zeitschrift, 2020
This publication synthesizes the results of the WIPAFF (WInd PArk Far Fields) project. WIPAFF focused on the far field of large offshore wind park wakes (more than 5 km downstream of the wind parks) located in the German North Sea.

Investigation of the floating IEA wind 15‐MW RWT using vortex methods Part II: Wake impact on downstream turbines under turbulent inflow

open access: yesWind Energy, 2022
The manuscript presents a novel numerical investigation on the impact of the wake of a floating IEA wind 15‐MW reference wind turbine (RWT) on downstream machines using a state‐of‐the‐art vortex solver coupled to a multi‐body code.

High-resolution CFD modelling of Lillgrund Wind farm [PDF]

open access: yes, 2013
We report on a fully dynamic simulation of Vattenfall’s Lillgrund offshore Wind Farm, with a focus on the wake effects of turbines on the performance of individual turbines, and of the farm as a whole.The model uses a dynamic representation of a wind ...

Wind Tunnel Testing of Yaw by Individual Pitch Control Applied to Wake Steering

open access: yesFrontiers in Energy Research, 2022
The yaw control of horizontal-axis wind turbines is the key point for wake redirection, which is expected to provide an improvement in the balance between wind farm production and loads.
