| 中文摘要: |
| 针对风力机叶片的结冰会严重影响风电机组的功率输出、危害风电机组的安全运行的情况，采用计算流体力学方法研究了典型的风力机翼型的结冰特性。首先，对攻角分别为0°，4°，8°的NACA0012翼型水滴撞击特性进行了计算，计算结果与文献实验结果吻合良好，表明了计算方法的正确性。在此基础上，对不同风速和不同温度下的典型风力机叶片表面的覆冰进行了模拟研究，得到了水收集系数和结冰厚度随温度和速度的变化趋势。结果表明：风速增加导致叶片表面结冰厚度增加，结冰附着面积增加；温度降低导致叶片表面结冰厚度增加；S801翼型的抗冰效果明显大于S802翼型的抗冰效果。研究结果有利于在低温环境中合理选择翼型，为降低叶片结冰危害程度提供参考。 |

| The icing of wind turbine blade will seriously affect the power output of wind turbine and endanger the safe operation of wind turbine. Computational fluid dynamics (CFD) is used to study the icing characteristics of typical wind wing. Firstly, the impact characteristics of water droplets on NACA0012 type turbine under different attack angle of 0°，4°，8°are calculated. The calculated results are in good agreement with the experimental results, which shows that the calculation method is correct, and, the ice coating on the blade surface of typical wind turbine with different wind speed and temperature was simulated, and the variation trend of water collection coefficient and ice thickness with temperature and velocity was obtained. The results show that: 1) with the increase of wind speed, the ice thickness of blade surface increases and the icing adhesion area increases; 2) with the decrease of temperature, the ice thickness of blade surface increases; and 3) the anti-ice effect of S801 airfoil is obviously greater than that of S802 airfoil. The research result helps logically select turbine under low temperature conditions, providing reference for lowering the blade icing hazard. |
