| Abstract: |
| As the development of the deep-water floating offshore wind farm has becoming more and more promising around the world,the study of the motion effect of floating platform on both the steady operation performance of the wind turbine and the aerodynamic loads analysis of the blade is of great importance.Based on three dimensional Navier-Stocks equation and k-ε Renormalization Group Method (RNG) turbulence model,which is very suitable for the rotational fluid flow,numerical simulations for the aerodynamic performance of National Renewable Energy Laboratory (NREL) of us 5MW offshore wind turbine blades have been done.The availability of the numerical model has been verified by comparing the numerical results with the corresponding design data from NREL.Furthermore,the complex nonlinear fluid-structure interaction between the blades and its surrounding airflow has been successfully investigated by using advanced sliding mesh technique to simulate the typical periodic motion of the floating platform.The effect of different motion amplitudes,and the effect of different motion periods have been studied.As a result,the law of the effects has been clarified in the view of physical mechanism.In summary,the main results of this work would play an active role in both the aerodynamic analysis of large floating offshore wind turbine and the motion performance design of the supporting floating platform. |
