以海上风电场高湿度环境为背景，假设湿空气为空气和小液滴的混合气体，基于欧拉壁面膜模型计算旋转状态下的三维风力机叶片的气动特性，着重分析三维旋转条件下水滴在叶片表面的分布及其对叶片气动性能的影响。研究发现，随湿度增大，叶片功率和推力减小。湿气主要影响风力机叶片的表面摩擦阻力，对叶片的表面压力系数影响较小。通过计算各种条件下叶片表面液滴收集、冲击特性，获得了叶片局部的液滴收集效率，通过分析液滴/颗粒在不同条件下碰撞冲击叶片表面的位置，为开发防水、防覆冰叶片涂层等有针对性的防护措施提供理论支持。

Offshore wind farm high humidity environment as the background, hypothesis of moist air is a mixture of dry air and small droplets, using Euler wall film model calculation of rotating three-dimensional wind turbine blade aerodynamic characteristics, analyses emphatically the influence of moisture on the aerodynamic performance of blade and the distribution of water droplets at blade surface under the condition of three-dimensional rotation. The study found that, with the increase of humidity, the blade power and thrust decreases. The main effect of moisture on the friction of blade surface, in comparison, the impact of pressure on the blade surface is small. By calculating the blade surface droplet collection efficiency at various conditions, it is helpful to prevent the wind turbine blades from the ice and remove the ice. Furthermore, understanding the location of droplets/particles collision the blade surface at various conditions is helpful to the blade manufacturers or the wind farm owner to have the targeted protection blade.
