The numerical simulations of fluid-structure interaction (FSI) of horizontal axis wind turbine in whole flow field are presented. The 5 kW wind turbine 3D model is designed according to blade element momentum (BEM) method. The simulations are carried out in Ansys using one way steady FSI by coupling CFX with Static Structure with total 7 × 106 tetrahedron unstructured meshes. The k-ω SST turbulent model is employed in CFX to precisely capture the flow field variation under different wind speeds. As wind speed increases from 7 to 16 m/s the power coefficient varies from 0.47 to 0.21 and the moment coefficient change from 4.3 × 10−2 to 8.2 × 10−2. The frequency of 1st flapwise will increase slightly as rpm goes up. The frequency of 1st edgewise is little higher than the 1st flapwise and not affected so much by the increasement of rotor rpm. Potential spots of resonance is near around rpm150.
