• 1016 Visualization of flow behavior in a swirling nozzle for micro bubble

抄録

Micro bubble is very small bubble that is smaller than 100 μm.It is used for reduction of liquid friction,and water quality purification.Swirling nozzle generate microbubble high efficiency.In future,it is hoped that diameter of microbubble is made smaller more and establish efficient method of generating microbubble.When air is supplied to swilling nozzle,the air column m a swilling nozzle oscillates periodically.This study is focus on the oscillation phenomenon of air column in swirling nozzle for microbubble generation.Air collum's oscillation is caught in detail by visualization,and The cause of an oscillation is solved.This phenomenon depends on the flow rate of supplying water and sucking air.
