Outline of Final Research Achievements

The purpose of this study is to understand the ionization mechanism of aerosol particle in air and collection mechanism of aerosol particles by ionic wind. We have developed a compact ionic wind generator which consists of a steel needle and a metal plate ground electrode and examined ionic wind characteristics such as ionic wind velocity and dust collection efficiency. The Ionic wind generator developed in this study generates strong air flow and is effective for aerosol particle collection. Using Comsol Multiphysics software, 2D simulation of an ionic wind around needle electrode in argon gas condition also has been carried out. Characteristics of ionic wind, such as electron and ion densities, inside argon gas have been clarified. As a future study, including all reactions occurring in the air are needed.
