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.

本研究旨在探讨离子化粒子在流动中的输运机制。实验中采用热线风速仪测量流量，采用能够测量空气中离子数的离子计数器测量密度。旋流增强了射流径向离子迁移率。同时发现，射流中离子的行为受湍流的影响，而不受库仑力和布朗运动的影响。
