DEVICE AND METHOD FOR GENERATING MICROBUBBLES IN A LIQUID USING HYDRODYNAMIC CAVITATION

摘要

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.
