At present, the study only discusses the icing law between supercooling 0—20K, which is half of the icing range of flight. To solve this problem, a diffusive interface phase field method which is suitable for large supercooling simulation of crystal is adopted, and anisotropy and thermal disturbance are considered. The characteristics of growth speed, morphology and tip radius in the supercooling range of 20—40K are quite concerned. The analysis of ice growth law shows its slope is significantly higher than the existing data of 0—20K. This is due to the increase of the tip’s curvature, which has a rapid decrease of thermal diffusion length, and promotes the thermal diffusion, and the increasing of curvature leading to the dynamic supercooling. Both of them lead to the increase of ice growth rate with supercooling. Using the ice growth law obtained to analyze the runback icing in aircraft, it is found that the ice runback distance is sensitive to the liquid water content (LWC) when the supercooling is larger than 20K and the LWC is large. Under this condition, the abnormal icing characteristics of fast growth and severe runback may occur simultaneously.
