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 impact on the downstream turbines. Large-Eddy Simulation (LES) is well adapted to this problem as the considered flow is 3D, complex and strongly unsteady. The state-of-the-art approach for taking into account the effect of the turbine on the flow is the Actuator Line (AL) method2,3. This method enables the use of Cartesian grids, which brings numerous advantages but prevents space adaptivity and limits the shape of the flow domain
