Predictive capability of actuator disk models for wakes of different wind turbine designs

To evaluate the predictive capability of actuator disk (AD) models in simulating wakes different wind turbine designs, we compare results AD simulation with those surface (AS) for EOLOS, NREL and a variant (i.e., NREL-V) designs. Two types are considered, i.e., AD-R AD-NR corresponding to model without rotational effects, respectively. For models, force coefficients both obtained from AS simulations. The compared It is observed that velocity profiles predicted by agree well predictions. turbulent kinetic energy Reynolds shear stress, differences appear at far wake locations (7D, 9D downwind where D rotor diameter) EOLOS NREL-V turbines. In case turbine, on other hand, there an overall good agreement except 3D turbine. Furthermore, modes using proper orthogonal decomposition simulations also presented each other, indicating distribution mode energy, location features patterns differ
