Adjoint Optimisation for Wind Farm Flow Control with a Free-Vortex Wake Model [PDF]
Renewable Energy, 2022 Wind farm flow control aims to improve wind turbine performance by reducing aerodynamic wake interaction between turbines. Dynamic, physics-based models of wind farm flows have been essential for exploring control strategies such as wake redirection and ...

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions
Journal of Physics: Conference Series, 2023 Abstract In this paper, we propose a new non-symmetric Gaussian wake model, which allows for different lateral expansions on the two sides of a wake to account for its interaction with neighbouring wakes. The proposed model is formulated following classical speed-deficit assumptions and momentum conservation.

Modeling the Wake of the Marquesas Archipelago [PDF]
Journal of Geophysical Research: Oceans, 2018 AbstractIn this study, a high‐resolution (∼2.5 km) numerical model was set up to investigate the fine‐scale activity within the region of the Marquesas archipelago. This has never been performed before. The robustness of the model results is assessed by comparison with remote sensing and in situ observations.

Progress on Offshore Wind Farm Dynamic Wake Management for Energy
Journal of Marine Science and Engineering, 2022 The wake management of offshore wind farms (OWFs) mainly considers the wake effect. Wake effects commonly occur in offshore wind farms, which cause a 5–10% reduction in power production.

Validation of wind turbine wake models with focus on the dynamic wake meandering model [PDF]
Journal of Physics: Conference Series, 2018 This analysis compares current wake models, such as the Sten Frandsen turbulence model, an engineering wind speed deficit and turbulence model developed by G. Chr. Larsen, the N. O. Jensen wind speed deficit description and three variations of the dynamic wake meandering (DWM) model to measurements from onshore wind farms. Special attention is given to

The Array Optimization of Vertical Axis Wind Turbine Based on a New Asymmetric Wake Model
Journal of Marine Science and Engineering, 2021 With the increasing demand for wind energy, the vertical axis wind turbine (VAWT) is attracting more and more attention. In order to design the VAWT array for better performance, the VAWT wake model needs to reflect the wake characteristics well.
