Modelling the aeroelastic response of slender structures to vortex-induced vibrations: Industry transfer through full-scale experimental campaign at a wind turbine

Larger and taller wind turbines are characterized by larger tip masses and longer rotor-nacelle assembly (RNA) masts. Both result in a lower natural frequency, lowering the critical wind speed and increasing the likelihood of vortex resonance. While freestanding towers, such as stacks, have been extensively investigated for vortex-induced vibration (VIV), the completed wind turbine as a structure has not yet been fully investigated for VIV.
