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 ...

Abstract: This paper presents previous and recent results obtained by the authors concerning the modification of the tip vortex cavitation of a finite span hydrofoil by drag-reducing polymer solutions. ...

Abstract: The behavior of air cavities formed in the tip vortex trailing from rectangular and elliptical planform hydrofoils has been examined both theoretically and experimentally. These cavities have ...

Abstract: The classical criterion for cavitation of bubbles is based on the assumption that the bubbles are subjected to a quasi-steady pressure change and that the non condensible gas within the cavity ...

Abstract: The effect of the planform of hydrofoils on tip vortex roll-up and cavitation has been investigated by testing three foils having the same NACA 16020 cross section but different shapes. One ...

Abstract: Sheet cavitation on a foil section and, in particular, its unsteady characteristics leading to cloud cavitation, were experimentally investigated using high-speed visualizations and fluctuating ...
