abstract

The aim of this study is to measure distribution of ionized particles in an axisymmetric jet. Recently, the effects of ionized particles, such as disinfection of bacteria and neutralizations of static electricity, are attracting much attention from many industry circles. Micro- and nano-size particles with electric charge are called “ionized particles” in this study. The ionized particles were usually carried to the objects in the air, which should be disinfected or neutralized, by a fluid force like an axisymmetric jet generated by a blower and a purge nozzle. High transportation of ionized particles improves the efficiency of the industrial products which use ionized particles. However, it is considered that behavior of ionized particle in axisymmetric jet is easily influenced by not only fluid force, but flow turbulence, Brownian motion and coulomb’s force. In this study, we measured ionized particle distribution in an axisymmetric jet by an ion count system which was a measuring device to count the number of ionized particles. The axisymmetric jet has an advantage of the high mass transportation and the diffusion capability by its flow characteristics. We conducted wind tunnel experiments to clarify the relationship between the axisymmetric jet and ionized particles. The experiment was performed in the flow velocity measurement by hot wire anemometer and the density measurement by an ion count system which was able to measure the number of ionized particle in the air. The results suggested that the behavior of ions in the jet was influenced by fluid force more than by the coulomb’s force. The aim of this study is to measure the distribution of ionized particles introduced into the axisymmetric jet.
