Développement et validation d'un modèle de cavitation à poche sur hydrofoil et pale d'hélice [PDF]

open access: yes, 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 ...

Experimental and Numerical Study of Cavitation Number Limitations for Hydrodynamic Cavitation Inception Prediction

open access: yesFluids, 2022
Hydrodynamic cavitation is the formation, growth and subsequent collapse of vapor bubbles in a moving liquid. It is extremely important to determine conditions of cavitation inception and when it starts damaging industrial equipment.

Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]

open access: yes, 1994
Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

Hydrodynamic cavitation-enhanced activation of sodium percarbonate for estrogen removal

open access: yes, 2023
The present paper investigated the potential of hydrodynamic cavitation (HC) as an effective tool for activating sodium percarbonate (SPC). The method's efficiency was demonstrated by effectively removing estrogens, which are pollutants that have adverse
