プラズマファインバブルの生成と計測

抄録

Fine bubbles generated by plasma in water that we named as “Plasma Fine Bubbles,” have high potential to generate long-life ultrafine bubbles due to electrical charges. It is shown that the residual bubbles formed by collapse of streamer gas channels which show a similar process of cavitation bubbles in various points such as growth, shrink, collapse, rebound, and fragmentation. There are also introductions about ultrafine bubbles measured by a dynamic laser scattering method, amount of electrical charge of plasma fine bubbles estimated by analyzing their movements under application of an intense electric field strength, evidence of hydrogen gas generation in laser/spark induced bubbles and a distinguishing method for between gas bubbles and solid particles.
