A Simple Model for Wake-Induced Aerodynamic Interaction of Wind Turbines

open access: yesEnergies, 2023
Wind turbine aerodynamic interactions within wind farms lead to significant energy losses. Optimizing the flow between turbines presents a promising solution to mitigate these losses.

A Calibration Procedure for an Analytical Wake Model Using Wind Farm Operational Data

open access: yesEnergies, 2020
Wind energy is one of the fastest growing renewable energy sources in the U.S. Wind turbine wakes change the flow field within wind farms and reduce power generation. Prior research has used experimental and computational methods to investigate and model

Large-eddy simulation of a 15 GW wind farm: Flow effects, energy budgets and comparison with wake models

open access: yesFrontiers in Mechanical Engineering, 2023
Planned offshore wind farm clusters have a rated capacity of more than 10 GW. The layout optimization and yield estimation of wind farms is often performed with computationally inexpensive, analytical wake models.

Aerodynamic Performance and Wake Flow of Crosswind Kite Power Systems

open access: yesEnergies, 2022
This paper presents some results from a computational fluid dynamics (CFD) model of a multi-megawatt crosswind kite spinning on a circular path in a straight downwind configuration. The unsteady Reynolds averaged Navier-Stokes equations closed by the k−ω

An alternative form of the super-Gaussian wind turbine wake model [PDF]

open access: yesWind Energy Science, 2020
A new analytical wind turbine wake model, based on a super-Gaussian shape function, is presented. The super-Gaussian function evolves from a nearly top-hat shape in the near wake to a Gaussian shape in the far wake, which is consistent with observations ...

Generalized coupled wake boundary layer model: applications and comparisons with field and LES data for two wind-farms [PDF]

open access: yes, 2016
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.

The curled wake model: a three-dimensional and extremely fast steady-state wake solver for wind plant flows [PDF]

open access: yesWind Energy Science, 2021
Wind turbine wake models typically require approximations, such as wake superposition and deflection models, to accurately describe wake physics. However, capturing the phenomena of interest, such as the curled wake and interaction of multiple wakes, in ...

Modelling Yawed Wind Turbine Wakes: Extension of a Gaussian-Based Wake Model

open access: yesEnergies, 2021
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.
