発明の名称 (英語) AIR BUBBLE GENERATION DEVICE, TUBULAR MEMBER, AIR BUBBLE GENERATION METHOD, AND METHOD FOR MANUFACTURING AIR BUBBLE GENERATION DEVICE コモンズ 新技術説明会
発明の概要(英語) This air bubble generation device is provided with a metal tubule (10) through which water passes, and a pump that pressure-feeds water containing a gaseous component into the metal tubule (10). Inside the metal tubule (10) is provided a throttle part (11) where the path for water is narrower than ahead and behind in the water flow direction. The cross-sectional shape of the throttle part (11), orthogonal to the flow direction, is rectangular. The gaseous component contained in the water is dissolved in the water by the pressure-feeding of the water into the throttle part (11), air bubbles are deposited by the decrease in pressure in the throttle part (11), a turbulent flow in the water is created in the throttle part (11), the air bubbles in the water are ruptured by shearing force from the turbulent flow, and the air bubbles are ruptured by shock waves caused by transonic flow occurring in the water exiting the throttle part (11).
