A research program known as “Action Concertee Cavitation” initiated in France in 1991 was aimed at investigating Tip Vortex Cavitation (TVC) in various experimental facilities operating over a large range of Reynolds numbers. An original method t

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 pressure measurements. Two sources of sheet cavitation i

La question de savoir dans quelle mesure la turbulence contribue ou non a la modification des conditions d'apparition de la cavitation a fait l'objet de nombreuses etudes ces dernieres annees. Pour preciser les choses a l'aide d'un venturi, on a deci

La cavitation se produit, si l'on utilise une definition simplifiee, quand la pression locale est egale ou inferieure a la pression de vapeur du liquide en circulation, quelle que soit la dimension de l'espace occupe par ce dernier. D'une maniere gen

It is by now well established that, for Reynolds numbers larger than those corresponding to the conditions of laminar-to-turbulent boundary layer transition over a flat plate (≈0.5 × 106) and for a variety of wing shapes and cross sections, desine

The flow structure in the confined space between the outer ring, the cage and the balls of a bearing is investigated using a large scale model allowing to perform visualizations, by tracer and dot-paint techniques, and velocity measurements, by Laser

Experiments regarding the modification of the foil geometry and/or active or passive mass injection in the vortex core have been performed to investigate the possibility of inhibiting tip vortex cavitation. The ejection at very low flow rates of drag

Jet swelling is shown to exist when a concentrated oil‐in‐water emulsion is ejected from a capillary tube into a stagnant fluid. The jet swells up to ten times the diameter of the capillary tube depending on the shear rate in the tube and the den

It is well known that a nucleus subject to a quasi-steady mean pressure drop can either oscillate or asymptotically grow depending the final pressure is above or blow the critical one. Recent investigations have shown that dynamically driven asymptot

The vapour production required to sustain a cavity leads to a temperature reduction at the interface. This temperature reduction, though quite small in the case of water, is significant in the case of cryogenic fluids. A method assuming that (i) the
