Abstract: A locally steep surface gradient or ?jump? may be expected on any steady surface current whose strength U decreases horizontally from supercritical (U > cmin) to subcritical (U < cmin), where cmin is the minimum phase ...

Abstract: An inviscid mechanism is proposed for the breakup of the jet in a plunging surface wave. Streamwise perturbations of the original surface are shown to grow rapidly owing to stretching of the thin jet and to drastic reduction ...

Abstract: Laboratory observations of short gravity waves of length about. 1 m by Koga show the occurrence of a downward flow separation near the wave crests, making angles of 10° to 50° with the horizontal. Kega's observations are ...

Abstract: We report the tuning of surface wetting through sacrificial nanoimprint lithography (SNIL). In this process, grown ZnO nanomaterials are transferred by imprint into a metallic glass (MG) and an elastomeric material, and ...
