Abstract

Taking a 300 kW wind turbine at Hunan Xuefeng Mountain Energy Equipment Safety National Observation and Research Station as the research object, this study establishes a three-dimensional rotating icing model for full-scale wind turbine blades based on a rotating reference frame and Eulerian gas-liquid two phase flow model. The model reveals the similarities and differences between rime and glaze ice accretion mechanisms. Through numerical simulations, the differences in ice morphology and mass accumulation between these two ice types are systematically compared, with particular emphasis on temperature effects. The results demonstrate that： 1） Temperature shows negligible influence on rime ice accretion but significantly affects the accretion area, morphology, and mass of glaze ice; 2） Rime ice forms streamlined shapes while glaze ice develops horn-shaped features, with the latter's accretion area decreasing but horn characteristics becoming more pronounced at lower temperatures; 3） The maximum ice thickness of rime ice increases monotonically along the blade span, whereas glaze ice exhibits distinct non-monotonic characteristics-under near-freezing conditions （e.g., -1 ℃）, unusual cases occur where mid-span ice thickness （at 0.60R） exceeds tip thickness （at 0.90R）; 4） Under identical icing durations, rime ice accumulates greater mass than glaze ice, with the latter showing a decelerating growth trend as temperature decreases.
