在风能资源较好的高纬度和高海拔地区,风电机组常常面临结冰问题。为研发高效的防除冰技术,有必要对风力机叶片表面结冰分布特征进行研究。该文借助回流式结冰风洞试验系统,开展了不同温度、翼型和材料条件下叶片表面结冰试验研究,并提出叶片表面结冰分布特征的评价方法。试验结果表明,翼型几何特征对叶片表面结冰分布影响较大;叶片材料对结冰分布的影响受环境温度影响较大。
Abstract
Ice oftenaccumulates on the surface of wind turbine blades in high latitude and high-eleration areas uith abundant, where wind energy resources . Ice alters the airfoil’s shape, compromises its aerodynamic performance, reduces the wind turbine’s output power, and can even lead to safety accidents. In order to develop efficient anti-icing and de-icing technologies, it is crucial to study the ice distribution characteristics on wind turbine blade surfaces. In this paper, icing experimental research was conducted on blades under different ambient temperatures, airfoils, and materials using the icing wind tunnel experimental system. Evaluation methods for the distribution characteristics of icing on the blade surface are proposed. The test results indicate that the airfoil’s geometric characteristics significantly affect the icing distribution on the blade surface, while the influence of blade material on icing distribution is significantly influenced by ambient temperature.
