Large-Eddy Simulation of wind turbines wakes including geometrical effects

Accurate simulation of wind turbine wakes is critical for the optimization of turbine efficiency and prediction of fatigue loads. These wakes are three-dimensional, complex, unsteady and can evolve in geometrically complex environments. Modeling these flows calls thus for high-quality numerical methods that are able to capture and transport thin...

Highly resolved Large-Eddy Simulation of wind turbine wakes

An horizontal axis wind turbine placed in a free stream develops a wake behind its rotor. Inside this wake, complex vortical instabilities are developing and can lead to turbulent structures generation1 . In order to predict performances and loads of wind turbines in wind farms, it is essential to accurately characterize these wakes and their...
