Abstract

In order to study the wind turbine wake and its eventual interactions with neighbouring wind turbines, several numerical and physical modelling approaches are used. Some model the wind turbine with the simplest model, that is the actuator disc concept, adding a drag source (i.e. pressure loss) within the surface swept by the blades (numerical [2], physical [1]). Some use the Blade Element Momentum Theory, which takes into account the blade rotation effect on the wake and the aerodynamic features of the blades [3]. Some use Large Eddy Simulation to compute the unsteady flow around the entire rotor [5]. In a wind resource assessment context, the latter one is not practical enough to be used since the computation times are extremely long.
