Superhydrophobic surfaces on supercritical airfoils: mitigating ice formation and enhancing performance

International Journal of Thermofluids
Superhydrophobic surfaces are characterized by low surface energy and micro- to nano-scale roughness. These properties cause fluids to slide over the surface, thereby reducing drag and adhesion, and resulting in a lower drag coefficient.
