中文摘要：
建立小型风力发电机叶片的三维流场模型,运用流体软件（FLUENT）分析旋转叶片在不同风速作用下的流动特性及气动特性的变化规律。结果表明：随风速的增大,叶片失速现象越严重,叶尖处的压强和流速均达到最大值;同时,风力发电机输出功率增大,叶尖速比和风能利用系数都减小。利用风能实验平台对小型风力发电机进行了实验测试,将所得数据与数值模拟结果进行对比分析,验证了数值模拟方案的准确性和有效性。
英文摘要：
A 3D flow field model of small wind turbine blade is established and the flow behavior and aerodynamic characteristics of wind turbine under the different wind speeds are analyzed by using fluid mechanics software FLUENT. The results show that： the blade stall phenomenon as the wind speed increases is becoming more serious, the maximal value of pressure and flow rate all occur in the blade tip. With the wind speed increasing, the output power rises, but both tip speed ratio and wind energy utilization coefficient reduce. Experiment test is also done for the wind turbine through wind energy experiment platform, and the experiment data is compared with the simulation result, they agree well with each other.
