| description | The discharge characteristics and bubble dynamics of argon multiple bubble jets, in which a streamer is generated by a DC pulsed discharge, have been experimentally clarified through visualization analysis. The decolorization characteristics of a methylene blue solution and the properties of a treated solution using multiple bubbles jets, including argon, oxygen and air, have also been clarified. There is complex streamer behavior in a bubble in which streamer propagation is along the interface of an issuing bubble. O and OH radicals during streamer discharge in Ar and O2 bubbles were detected clearly near the interface of a breaking up bubble by spectroscopic measurement. Finally, the decolorization efficiency by O and OH radicals and ozone in a pulsed discharge multiple bubble jets are estimated. |
