| Research Abstract |
The novel DBD plasma tube was originally developed for water treatment. The ozone eneration rate, the conversion rate of methylene blue mist and its energy efficiency were clarified for operating conditions such as applied voltage, frequency, flow rate and tube length. Furthermore, the water treatment method spraying acetic acid solution into the coaxial cylinder DBD tube was investigated in detail. The power consumption, generated radicals, decomposition process and high decomposition rate were clarified. Finally, the novel numerical method using plasma-gas-doroplet three phase reactive model was proposed based on water treatment experiment. There were good agreement of dissolved species into the droplet between numerical simulation and experiment.
