Surging Wind Turbine Simulations with a Free Wake Panel Method

Abstract We investigate the aerodynamics of a surging wind turbine with numerical simulations based on free wake panel method. start by demonstrating method’s capability to simulate plunging airfoil, which provides some insights that are later used interpret results rotor. then validate method non-surging and discuss strengths weaknesses our approach. Next, we focus UNAFLOW case: was modelled experimentally various methods. Good agreement experimental data is observed for amplitude phase thrust surge motion. For first time, achieve accurately reproduce verified effects Finally, extend beyond frequency range experiments reach do not follow quasi-steady response. Using airfoil data, justify behavior in non-linear range. Our work seeks contribute different pool case, while extending analysis conditions have been simulated before.
