AIR LAYER AND HYDROPHOBIC DRAG REDUCTION AND PREFERENTIAL GUIDANCE AND RECOVERY OF GAS WITH ENGINEERED SURFACES

摘要

Disclosed herein are a method and a system for forming an air layer over a portion of an engineered surface, wherein the air layer is formed with a reduced flux and preferentially steering gas away from, or toward, a specific location by way of a hydrophobic surface, a hydrophilic surface, and/or a structured surface. Moreover, disclosed are a method and a system for recovering or separating a portion of the gas or other fluid layer.
