摘要
基于叶素动量理论,通过Matlab/Simulink建立双圆盘-多流管数学模型。给出一种分析H-型垂直轴风力发电机组空气动力学特性的方法,利用该数学模型得到不同实度及叶尖速比时风力机具有的攻角特性、切向力特性、法向力特性。通过与实验数据和单流管模型计算结果进行对比,证实了该方法的准确性及优越性。
Based on the mathematical model was theory of blade element momentum, a double round plate-multiple stream tube established using Matlab/Simulink program, which could analyze aerodynamic characteristics of H-type vertical axis wind turbine. The attack angle characteristic, tangential force characteristics, normal force characteristics for different solidity and tip speed ratio of wind turbine were obtained using the mathematic model, which were compared with experiment data and the result of single stream tube model. The results confirm that the method is accurate and superior.
