Research Abstract

The aim of this study is to investigate the transportation mechanism of ionized particle in flow. The experiment was performed in the flow measurement by hot wire anemometer and the density measurement with an ion counter which was able to measure the number of ions in air. Ion mobility for radial direction of the jet was enhanced by the swirl flow. Also it was found that the behavior of ions in jet was influenced by turbulence rather than by the coulomb's force and Brownian motion.
