The Importance of Wake Meandering on Wind Turbine Fatigue Loads in Wake [PDF]
Energies, 2021 Considering loads when optimizing wind-farm layouts or designing farm-control strategies is important, but the computational cost of using high-fidelity wake models in the loop can be prohibitively high.

Wind tunnel experiments on wind turbine wakes in yaw: redefining the wake width [PDF]
Wind Energy Science, 2018 This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and turbine specifications.

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.

The impact of turbulence and turbine operating condition on the wakes of tidal turbines [PDF]
Renewable Energy, 2021 Before initiating a study on the interaction of multiple wakes, it is imperative that turbine wake hydrodynamics are studied in isolation. In this paper CFD computer simulations of downstream turbine wakes have been run using a scale-resolving hybrid turbulence model known as a detached eddy simulation.

Instabilities in tidal turbine wakes [PDF]
Proceedings of the European Wave and Tidal Energy Conference, 2023 We report on the observation of vortex instabilities in the wake of a tidal turbine undergoing harmonic unsteady axial inflow (e.g. due to surface waves). The work was carried out using unsteady RANS (URANS) modelling using the open-source CFD software OpenFOAM, using the `pimpleDyMFoam' solver.

Multirotor wind turbine wakes [PDF]
Physics of Fluids, 2019 To fulfill the increasing need for large power generation by wind turbines, the concept of multirotor wind turbines has recently received attention as a promising alternative to conventional massive single-rotor wind turbines. To shed light on the viability of this concept, large-eddy simulation is employed in this study to compare wake flow properties

The stability of wakes of floating wind turbines
Physics of Fluids, 2022 Floating offshore wind turbines (FOWTs) are subjected to platform motion induced by wind and wave loads. The oscillatory movement trigger vortex instabilities, modifying the wake structure and influencing the flow reaching downstream wind turbines. In this work, the wake of a FOWT is analyzed by means of numerical simulations and a comparison with ...

Wake Behavior behind Turbine Cascades in Compressible Two-Dimensional Flows
International Journal of Rotating Machinery, 2005 The goal of the paper is to describe wake parameters of wakes from turbine cascades in compressible flows especially in planes where the leading edge of the following blade row would be located. Data from experiments with turbine cascades in compressible
