基于叶素动量复合理论的小型风力机设计与实验

Design and Experiment of a Small Scale Horizontal-axis Wind Turbine by Blade Element Momentum Theory

利用叶素动量复合理论设计开发了在低转速下具有高输出力矩的小型水平轴螺旋桨式风力机。同时,自行编制了风力机设计程序,并根据模拟计算结果设计制作了一台具有6枚叶片的小型风力机风轮模型,在不同风速下进行了风洞实验,测试了风力机的输出力矩和功率性能,并将实验结果进行了分析。

The object of this study is to design and develop the small scale horizontal - axis wind turbine with high torque performance at low rotation speed based on the blade element momentum theory. According to the simulating results by the program developed in this study, a test model turbine with 6 blades was designed and made. Wind tunnel tests were made under different wind speeds, and the torque and power performance of the test model were measured.
