Study on the Aerodynamic Performance of Floating Offshore Wind Turbine Considering the Tower Shadow Effect

The aerodynamic performance of the floating offshore wind turbine (FOWT) is obviously affected by motion platform, and becomes much more complicated considering effect tower shadow. In view this, this paper aims at investigating with without a under three most influential motions (surge, pitch yaw) computational fluid dynamic (CFD). results show that power reduced 1.58% to 2.47% due shadow motions, pressure difference distribution interfered yaw concentrates root tip blade. addition, degree interference on wake flow field different resulting in complex structure. These conclusions can provide theoretical basis technical reference for optimal design turbines.
