Drag reduction using superhydrophobic surfaces is one of the most significant strategies to reduce energy consumption and drag losses in marine vessels and fluid channels. However, the trapped air at a solid-liquid interface on superhydrophobic surfaces usually becomes unstable under high flow speed...
