摘要：
In order to study the influence of deflected wake of upstream wind turbine on aerodynamic characteristics of downstream wind turbine, large-eddy simulation was coupled with an actuator line technique based on OpenFOAM open-source toolbox as numerical method. Influence of the deflected wake on the aerodynamic characteristics of the downstream wind turbine and the total power output of the wind field were studied by changing the yaw angle of the upstream wind turbine to deflect wake. The study found that as the yaw angle of the upstream wind turbine increases, the total power of the wind farm first increases and then decreases, when the yaw angle of the upstream wind turbine is 30°, the output power of the wind farm is the largest, compared with situation of upstream wind turbine is not yawing, the total power increase by 23.6%. The average value of the aerodynamic load of the downstream rotor increases, the amplitude first increases and then decreases, and the change of the aerodynamic load is related to the 3 times rotation frequency of the rotor; The axial force and tangential force at different sections of the wind turbine blade increase first and remain unchanged. The corresponding azimuth interval of the maximum value of the force is gradually increasing, and the corresponding azimuth interval of the minimum value is gradually decreasing.The results can provide a reference exploring ways to improve the power output of wind turbines and the study of the aerodynamic characteristics of wind turbines under complex inflow conditions. © 2019 Chin.
