Factors which forms a flow field in an electrostatic precipitator (ESP) is a shape of ESP, a gas flow velocity and an ionic wind. Ionic wind is a flow that occurs ions generated by corona discharge collide with air molecules. About the influence on the particles of the ion wind, it is not clarified enough. It is important for the clarification of a particle collecting process, and improvement in particle collecting efficiency to clarify the interaction in ESP including an ion wind. In this study, it analyzed the particle behavior of ESP by using PIV (particle image velocimetry) analysis. The Particle Image Velocimetry method which can perform non-contact measurement and multi-point coincidence measurement was used for the analysis of a particle behavior. This paper reports a PIV analysis result about an ion wind and the particle movement velocity.
