An alternative form of the super-Gaussian wind turbine wake model
Wind Energy Science, 2020 . A new analytical wind turbine wake model, based on a super-Gaussian shape function, is presented. The super-Gaussian function evolves from a nearly top-hat shape in the near wake to a Gaussian shape in the far wake, which is consistent with ...

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
