室内空気清浄のためのコロナ放電励起非熱プラズマによるイオンクラスタ―形成

抄録

During pulsed corona discharges, both negative and positive ions react with moisture to generated cluster ions. These cluster ions are considered to be useful for cleaning hazardous materials such as hazardous pollutants and allergen. In this paper, for such type of ions generation devices, numerical simulation is carried out on the cluster ions formation. The behavior of streamer evolution and cluster formations are simulated well, and it is clarified that the clustering progresses toward H₃O⁺(H₂O)₄ and O₂ ^- (H₂O)₄. Ions number densities obtained in the experiment are smaller than the calculated ones because some differences between the numerical model and experiment exit and the ions may be lost near in the path of the chamber.
