Abstract: Drag reduction caused by ejecting additive solutions from a slot into a pure-water boundary layer on a flat plate has been systematically studied. Results include drag measurements for a plane ...

Abstract: Internal waves produced by a ship traveling faster than the fastest internal waves (supersonic case) were investigated experimentally in our laboratory in a wide tank using averaging conductivity ...

Abstract: A linearized theory is presented for the dead-water phenomena. A two-layer fluid model of finite depth is assumed and the solutions for both the wave resistance, as well as the interface and ...

Abstract: Various effects of polymer additives, other than drag reduction, are discussed with an emphasis on lift effects on two-dimensional hydrofoils. In reviewing effects of additives in homogeneous ...
