On the collapse structure of an attached cavity on a three-dimensional hydrofoil / Evert-Jan Foeth in Transactions of the ASME . Journal of fluids engineering, Vol. 130 N° 7 (Juillet 2008) 

Public ISBD [article]  in Transactions of the ASME . Journal of fluids engineering > Vol. 130 N° 7 (Juillet 2008) . - 9 p. Titre : On the collapse structure of an attached cavity on a three-dimensional hydrofoil Type de document : texte imprimé Auteurs : Evert-Jan Foeth, Auteur ; Tom van Terwisga, Auteur ; Cas van Doorne, Auteur Année de publication : 2014 Article en page(s) : 9 p. Note générale : Fluids engineering Langues : Anglais (eng) Mots-clés : Three-dimensional  twisted  hydrofoil;  collapse Résumé : A three-dimensional twisted hydrofoil with an attached cavitaty closely related to propellers was observed with a high-speed camera at the University of Delft Cavitation Tunnel. Reentrant flow coming from the sides of the cavity aimed at the center plane—termed side-entrant flow—collided in the closure region of the cavity, pinching off a part of the sheet resulting in a periodic shedding. The collapse of the remainder of the sheet appears to be a mixing layer at the location of the colliding reentrant flows. Collision of side-entrant jets in the closure region of a cavity is identified as a second shedding mechanism, in addition to reentrant flow impinging the sheet interface at the leading edge.
