Abstract
There is provided a microbubble generating method including: supplying a gas to a rotatorwhile rotating the rotatorin a liquid; injecting the gas into the liquid from bubble injection holes formed in the surface of the rotator; and applying a shear force, produced by the relative movement between the liquid and the rotator, to gas bubbles present on and in the vicinity of the surface of the rotatorto generate microbubbles. The microbubble generating method can easily generate a large amount of microbubbles without forcibly creating a swirling flow of fluid.
