Nonlinear inviscid aerodynamics of a wind turbine rotor in surge, sway, and yaw motions using a free-wake panel method

Abstract. We investigate the aerodynamics of a surging, heaving, and yawing wind turbine with numerical simulations based on free-wake panel method. focus UNAFLOW (UNsteady Aerodynamics FLOating Wind turbines) case: surging which was modeled experimentally various methods. Good agreement experimental data is observed for amplitude phase thrust surge motion. achieve results wake that accurately reproduce verified effects then extend our beyond frequency range experiments reach do not follow quasi-steady response surge. Finally, are done in yaw heave motion, impact motion blade examined. Our work seeks to contribute different method pool case while extending analysis conditions have been simulated before providing insights into nonlinear aerodynamic
