<p>Provided is a micronanobubble generation method, a micronanobubble generator, and a micronanobubble generation device in which microbubbles are generated in a stable manner despite the pump being small and the amount of gas supplied being small, and at the same time, some of the generated microbubbles are efficiently made into nanobubbles in the same action. This method for generating micronanobubbles includes a step for generating a gas-liquid two-phase swirl flow in a two-phase flow swirl-type micronanobubble generator, a step for releasing the gas-liquid two-phase swirl flow into an external liquid from a releasing hole of the micronanobubble generator, and a step for moving microbubbles in the released gas-liquid two-phase swirl flow along the outer wall surface of the micronanobubble generator.</p> |
