(EN) DEVICE AND METHOD FOR GENERATING MICROBUBBLES IN A LIQUID USING HYDRODYNAMIC CAVITATION
(FR) DISPOSITIF ET PROCEDE PERMETTANT DE GENERER DES MICROBULLES DANS UN LIQUIDE PAR CAVITATION HYDRODYNAMIQUE
Abrégé
(EN)
A device (10) and method of generating microbubbles in a liquid by feeding the liquid and gas through a flow-through channel (25) at respective flow rates and passing the liquid and gas through at least two local constrictions (85, 95) of flow to create hydrodynamic cavitation fields (80, 90) downstream from each local constriction (85,95) of flow to thereby generate microbubbles.
(FR)
L'invention concerne un dispositif et un procédé permettant de générer des microbulles dans un liquide. Le procédé selon l'invention consiste à faire circuler le liquide ainsi qu'un gaz dans une chambre à écoulement continu, à des vitesses d'écoulement respectives, et à faire passer le liquide et le gaz à travers au moins deux zones locales d'écoulement étranglées afin de créer des champs de cavitation hydrodynamique en aval desdites zones étranglées, pour y générer des microbulles.
