摘要: 以融冰界面位移与相变传热理论为基础,考虑了玻璃纤维增强树脂复合材料层和冰层的升温蓄热、界面冰层融化相变潜热以及冰层与周围空气的对流传质、对流换热和辐射换热等影响,提出了一种基于高分子电热膜的电热除冰功率密度计算的数学模型。对特定除冰模型进行了功率密度的计算,并通过模拟特定环境下的实际除冰实验对计算结果的准确性进行了验证,计算结果与实验结果吻合较好。

Abstract: In this paper, a heating power density computational model, based on melting ice interface displacement and phase change heat transfer theory, is established for wind turbine blade de-icing system using polymer electric thermal film. This model takes in account the thermal storage of GFRP layers and ice, interface melting ice latent heat and convection heat transfer, convective mass transfer and radiation heat transfer of air exchange with the surrounding environment. In order to verify the proposed model, the heating power density under specific environment was calculated and the corresponding deicing experiments using GFRP plates containing polymer electric heating film were carried out. The results show good agreements between the mathematical model and experiment.

Key words: polymer electric heating film, electrically heated deicing, power density, computational model
