Active Gas-Supplied Superhydrophobic Porous Grooved Interfaces for Broadening the Effective Range of Underwater Grooved Drag Reduction

Abstract Reducing underwater drag is important for improving the endurance and energy efficiency of marine equipment. Grooved surfaces and superhydrophobic coatings hold promise for drag reduction; however, conventional grooves require scale matching with near-wall turbulent stru...
