本文将动量-叶素理论推广应用于计算水平轴风车叶轮有侧偏角或上仰角时的气动力。计算结果与实验数据比较表明:这种计算方法简单快速,并有一定的准确度。所得结果对合理设计小型水平轴风车侧偏式或上仰式限速机构很有用。
In this paper, momentum-valence element theory is applied to the calculation of the aerodynamic forces when the horizontal axis wind turbine impellers have a slip angle or elevation angle. Comparing the calculated results with the experimental data, it shows that this method is simple and fast with a certain degree of accuracy. The results are useful for the rational design of small horizontal-axis windmill-side or up-side speed limit mechanism.
