Abstract In order to investigate the mechanism underlying the impact of superhydrophobic surfaces on the icing and anti-icing characteristics of fairings, this study focuses on marine gas turbine fairings as the research subject and employs numerical simulation methods to examine how droplet diameter and impact velocity influence the icing characteristics of superhydrophobic surfaces on fairings. The findings reveal that larger droplet radii are more prone to freezing onto superhydrophobic surfaces, resulting in a more stable ice sheet formation. Moreover, higher droplet velocities facilitate easier freezing on superhydrophobic surfaces, leading to larger frozen areas, thicker ice sheets, and more pronounced ice peaks. Additionally, differences in impact angles prevent droplets from freezing.
