Abstract To improve wind turbine design, low order models that accurately predict the aerodynamic performance are desirable. Dynamic stall dominates the aerodynamic performance, the robustness, and the wake dynamics of vertical axis wind turbines. To better assess the dynamic stall onset and its associated unsteady effects, this talk will present experimental measurements on the leading edge suction on a sinusoidal pitching airfoil with also time-resolved particle image velocimetry. During the dynamic stall stage, we linked the flow dynamics with the evolution of the leading edge suction.

Bio Julien Deparday is interested in experimental studies on unsteady aerodynamics and fluid-structure interaction. During his PhD, he conducted full-scale experimental studies of fluid-structure interaction on downwind sails at the Naval Academy Research Institute, France. He is now a post-doctoral researcher at UNFoLD and works on unsteady aerodynamics.
