Abstract

For further design and development of wind turbines, accurate prediction of aerodynamic performance is of great significance. The aerodynamic performances of large-scale floating offshore wind turbine blades NREL 5-MW of OC4 are simulated with the effect of tower, the transient solver pimpleDyMFoam in open-source software OpenFOAM is employed, the sliding mesh method is used, and the
simulation under different wind speeds are conducted. The time history of thrust and torque are obtained, the wake vortexes are available. Discussions about tower-blade interaction, rotation effects are done in thisresearch work.
