Using high-fidelity large-eddy simulation coupled with Actuator Line model, we explore three conditions for Vestas V80 turbine, both without yaw. The results indicate that meandering occurs predominantly along deflected axis. Despite varying deficits behaviors, neutral stable exhibit similar trajectories during yawed operations. Spectral analysis reveals...
