Micro-Trenches That Retain Trapped Gas Under High-Speed Water Flows (UCLA Case No. 2023-204)
Summary: UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed a design of microstructured surfaces capable of retaining air pockets under water at flow speeds above 10 knots so that watercraft can travel with a reduced drag. Background: A major challenge limiting efficiency and speed of watercraft is the friction...
