Volumetric LiDAR Scanning of a Wind Turbine Wake and Comparison with a 3D Analytical Wake Model

Fernando Porté Agel, Fernando Carbajo Fuertes

A correct estimation of the future power production is of capital importance whenever the feasibility of a future wind farm is being studied. This power estimation relies mostly on three aspects: (1) a reliable measurement of the wind resource in the area, ...

Flow adjustment in a finite size wind farm in a neutral ABL

Varun Sharma, Marc Parlange, Marc Calaf Bracons

It is now well-recognized that in the presence of an asymptotically large wind farm, the ABL adjusts to this ‘enhanced’ roughness to form a fully developed ‘wind turbine array boundary layer’ (WTABL), where the driving force of the ABL is in balance with t ...

Experimental and theoretical study of wind turbine wakes in yawed conditions

Fernando Porté Agel, Majid Bastankhah

This work is dedicated to systematically studying and predicting the wake characteristics of a yawed wind turbine immersed in a turbulent boundary layer. To achieve this goal, wind tunnel experiments were performed to characterize the wake of a horizontal- ...

Hub vortex instability within wind turbine wakes: Effects of wind turbulence, loading conditions, and blade aerodynamics

François Gallaire, Giacomo Valerio Iungo, Francesco Viola

The near wake of wind turbines is characterized by the presence of the hub vortex, which is a coherent vorticity structure generated from the interaction between the root vortices and the boundary layer evolving over the turbine nacelle. Bymoving downstrea ...

Data-driven RANS for simulations of large wind farms

Giacomo Valerio Iungo, Francesco Viola

In the wind energy industry there is a growing need for real-time predictions of wind turbine wake flows in order to optimize power plant control and inhibit detrimental wake interactions. To this aim, a data-driven RANS approach is proposed in order to ac ...

Effects of incoming wind condition and wind turbine aerodynamics on the hub vortex instability

François Gallaire, Giacomo Valerio Iungo, Francesco Viola

Dynamics and instabilities occurring in the near-wake of wind turbines have a crucial role for the wake downstream evolution, and for the onset of far-wake instabilities. Furthermore, wake dynamics significantly affect the intra-wind farm wake flow, wake i ...

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 ...

A New Analytical Model For Wind-Turbine Wakes

Fernando Porté Agel, Majid Bastankhah

A new analytical wake model is proposed and validated to predict the wind velocity distribution downwind of a wind turbine. The model is derived by applying conservation of mass and momentum and assuming a Gaussian distribution for the velocity deficit in ...

Prediction of the hub vortex instability in a wind turbine wake: stability analysis with eddy-viscosity models calibrated on wind tunnel data

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

The evolution and downwind recovery of wind turbine wakes are crucial factors for the evaluation of waketo-wake interactions within a wind farm and, in turn, for the prediction of wind power harvesting. Wind turbine wakes are affected by the design of wind ...
