摘　　要：采用Fluent和FENSAP-ICE相结合的方法对寒区海上风力机叶片结冰开展数值模拟,选取液态水含量作为敏感参数,分析了液态水含量的变化对叶片结冰厚度、结冰量和结冰外形的影响。结果表明,液态水含量在0.05~0.25 g·m^(-3)范围内,随着液态水含量的增加,叶片表面的结冰量和结冰厚度逐渐增加;液态水含量并不影响叶片表面的结冰类型和结冰生长趋势;冰与叶片的吸附面也不随液态水含量变化而发生改变。This study used Fluent and FENSAP-ICE to simulate the ice formation of offshore wind turbine blades in cold regions.The liquid water content was selected as a sensitive parameter,and the influence of the change of the liquid water content on the thickness,amount and shape of ice formation was analyzed.The results showed that when the liquid water content was in the range of 0.05–0.25 g·m^(-3),the amount and thickness of ice on the blade surface increased gradually.The liquid water content did not affect the type and growth trend of ice on the blade surface.Moreover,the adsorption surface between the ice and the blade did not change with the variation of the liquid water content.
