Outline of Final Research Achievements

The objective of this research is to develop the innovative air conditioner based on the technology establishment of droplets automization and ozone generation using kerosene based magnetic fluid and water based magnetic fluid respectively in the AC electric field, furthermore, droplets removal on a hydrophilic insulator with pulsed discharge. In low AC frequency the oscillation of magnetic fluid spike, ejections of small droplets and liquid thread from magnetic fluid spike are clarified. In high frequency ozone generation efficency is clarified as a function of frequency for air purification. Furthermore, droplets removal characteristics utilizing Joule heating evaporation on a hydrophilic insulator with pulsed discharge is also clarified by discharge visualization. Finally, the presence of OH radical generation was confirmed for decomposition of waste water droplets.
