Stochastic Wake Modelling Based on POD Analysis [PDF]
In this work, large eddy simulation data is analysed to investigate a new stochastic modeling approach for the wake of a wind turbine. The data is generated by the large eddy simulation (LES) model PALM combined with an actuator disk with rotation ...

A non-symmetric Gaussian wake model for lateral wake-to-wake interactions
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.

Modelling Yawed Wind Turbine Wakes: Extension of a Gaussian-Based Wake Model [PDF]
Yaw-based wake steering control is a potential way to improve wind plant overall performance. For its engineering application, it is crucial to accurately predict the turbine wakes under various yawed conditions within a short time. In this work, a two-dimensional analytical model is proposed for far wake modeling under yawed conditions by taking the ...

Modeling the Wake of the Marquesas Archipelago [PDF]
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.

The objective of this paper is to investigate the ability of analytical wake models to estimate the wake effects between wind turbines (WTs). The interaction of multiple wakes reduces the total power output produced by a large offshore wind farm (LOFWF).

Joukowski’s wake model for tip-splitting rotors [PDF]
Abstract The interaction between a tip vortex and a solid surface is responsible for premature structural component fatigue in wind turbines and undesirable noise in helicopter rotors during low speed and descending flight. One noise reduction strategy uses a modified airfoil to split and spread the vorticity in two tip vortices.

Progress on Offshore Wind Farm Dynamic Wake Management for Energy
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.

Generalized coupled wake boundary layer model: applications and comparisons with field and LES data for two wind-farms [PDF]
We describe a generalization of the Coupled Wake Boundary Layer (CWBL) model for wind-farms that can be used to evaluate the performance of wind-farms under arbitrary wind inflow directions whereas the original CWBL model (Stevens et al., J.
