| 中文摘要: |
| 随着风力机的大型化，风电机组对环境的影响不容忽视，必须对风力机气动噪声进行预测和控制。选取基于NACA、DU翼型的某风力机叶片作为研究基准，采用修正BPM半经验模型计算叶片的气动噪声特性，通过改变翼型族、弦长、机组运行状态、风切变指数、来流风向参数，研究叶片外形几何参数、机组运行工况对叶片气动噪声源的影响。计算结果从多个角度总结出水平轴风力机叶片气动噪声的变化规律，为开发高效低噪风电叶片提供参考。 |
| 英文摘要: |
| With the size of wind turbine getting larger, the impact of wind turbines on the environment cannot be ig-nored. Therefore, the prediction and control of wind turbine aerodynamic noise should be conducted. A tur-bine blade with NACA and DU series airfoils was selected as the research baseline. The modified BPM semi-empirical model was used to calculate aerodynamic noise characteristics of blades. The influence of blade shape parameters and turbine operating conditions on aerodynamic noise of horizontal wind turbine blades was studied, through modifying the factors such as airfoil series, chord, wind turbine operating states, wind shear index, inflow direction, etc. Simulation results showed disciplines of varying of the aerodynamic noise from different aspects, which provides a reference for the development of high efficiency and low noise wind turbine blades. |
