Combined Effect of Rotational Augmentation and Dynamic Stall on a Horizontal Axis Wind Turbine
Energies, 2019 Rotational augmentation and dynamic stall have been extensively investigated on horizontal axis wind turbines (HAWTs), but usually as separate topics. Although these two aerodynamic phenomena mainly determine the unsteady loads and rotor performance, the
