Développement et validation d'un modèle de cavitation à poche sur hydrofoil et pale d'hélice [PDF]
, 2008 FRANCAIS Un module de cavitation à poche a été développé et implémenté sur un code potentiel hélice. La méthode pour représenter la cavitation à poche utilise les vitesses de transpiration qui permettent de dévier la condition de glissement sans ...

Cavitation Threshold of Microbubbles in Gel Tunnels by Focused Ultrasound [PDF]
Ultrasound in Medicine & Biology, 2007 The investigation of inertial cavitation in micro-tunnels has significant implications for the development of therapeutic applications of ultrasound such as ultrasound-mediated drug and gene delivery. The threshold for inertial cavitation was investigated using a passive cavitation detector with a center frequency of 1 MHz.

Experiment with Axiom Propeller in Cavitation Tunnel [PDF]
Journal of the Korean Society of Marine Environment & Safety, 2014 The Axiom propeller is a unique 3 bladed propeller and it enables to generate the same amount of thrust going ahead as it does going astern because of its ‘s’ type skew-symmetric blade section. A earlier variant of the design (Axiom I propeller) performed a low propeller efficiency, maximum 35 % efficiency, and further blade outline design was carried ...

International Journal of Naval Architecture and Ocean Engineering, 2023 The Large Eddy Simulation (LES) method coupled with a Schnerr and Sauer cavitation model was adopted to simulate the unsteady cavitating flow around a Delft Twist 11 (Twist11) hydrofoil. We proposed a novel aggressiveness indicator to predict the risk of

The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy [PDF]
, 2011 Recent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue
