摘　　要：利用FLUENT软件对750 kW风机叶片在额定风速和12个非额定风速工况下进行气动性能的数值模拟计算,计算叶轮的受力、扭转力矩、输出轴功率和风能利用效率等性能参数;绘制功率曲线图,并和风机叶片实测功率曲线进行比较,验证了风力机气动性能数值模拟的可靠性以及叶片建模的合理性。观察叶轮表面的压强分布、流速分布、湍流强度、流速矢量等流态图,对风力发电机叶片的数值模拟计算结果进行分析,可进一步验证所设计的风力发电机叶片气动性能的优劣,为风力机叶片的设计、改型和研发工作提供技术参数和指导。The aerodynamic performance of 750 kW wind turbine blades was simulated and analyzed using FLUENT software in the rated wind speed and 12 unrated wind speed working conditions. The stress of the impeller, twisting moment, power of output shaft and wind energy efficiency were calculated. Power curve was drawn, and it was compared with the measured power curve to verify reliability of the wind turbine aerodynamic performance simulation and rationality of blade modeling. The flow pattern figures about pressure distribution, velocity distribution, turbulence intensity and velocity vector were observed, and the blade simulation results were analyzed. So the quality of the designed wind turbine blade can be confirmed, and it provides technical parameters and guidance for wind turbine blade design and modifications.
