Modeling turbine wakes and power losses within a wind farm using LES: An application to the Horns Rev offshore wind farm

Fernando Porté Agel, Yu-Ting Wu

A modeling framework is proposed and validated to simulate turbine wakes and associated power losses in wind farms. It combines the large-eddy simulation (LES) technique with blade element theory and a turbine-model-specific relationship between shaft torq ...

Interaction between large wind farms and the atmospheric boundary layer

Fernando Porté Agel, Yu-Ting Wu, Hao Lu

Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines is of great importance for optimizing the design and efficiency of wind farms. This study first focuses on recent efforts to develop and validate a large-e ...

Effects of wind direction and wind farm layout on turbine wakes and power losses in wind farms: An LES study

Fernando Porté Agel, Yu-Ting Wu

A recently-developed large-eddy simulation (LES) framework is validated and used to investigate the effects of wind direction and wind farm layout on the turbine wakes and power losses in wind farms. The subgrid-scale (SGS) turbulent stress is parameterize ...

Simulation of Turbulent Flow Inside and Above Wind Farms: Model Validation and Layout Effects

Fernando Porté Agel, Yu-Ting Wu

A recently-developed large-eddy simulation framework is validated and used to investigate turbulent flow within and above wind farms under neutral conditions. Two different layouts are considered, consisting of thirty wind turbines occupying the same total ...

Springer Netherlands2013

In this thesis, we develop a new large-eddy simulation (LES) framework to simulate atmospheric boundary layer (ABL) flows through wind turbines and wind farms. A Lagrangian scale-dependent dynamic model is used to compute the Smagorinsky model coefficient ...

Field Measurements of Wind Turbine Wakes with Lidars

Fernando Porté Agel, Giacomo Valerio Iungo, Yu-Ting Wu

Field measurements of the wake flow produced from a 2-MW Enercon E-70 wind turbine were performed using three scanning Doppler wind lidars. A GPS-based technique was used to determine the position of the wind turbine and the wind lidar locations, as well a ...

Interaction between large wind farms and the atmospheric boundary layer

Fernando Porté Agel, Yu-Ting Wu, Hao Lu

2012

A numerical study of atmospheric turbulence effects on wind-turbine wakes is presented. Large-eddy simulations of neutrally-stratified atmospheric boundary layer flows through stand-alone wind turbines were performed over homogeneous flat surfaces with fou ...

Large-eddy simulation of atmospheric boundary layer flow through wind turbines and wind farms

Fernando Porté Agel, Yu-Ting Wu, Hao Lu

Accurate prediction of atmospheric boundary layer (ABL) flow and its interactions with wind turbines and wind farms is critical for optimizing the design (turbine siting) of wind energy projects. Large-eddy simulation (LES) can potentially provide the kind ...
