Enhancement of Ionized Particle Mobility by Flow Control

本研究旨在探讨离子化粒子在流动中的输运机制。实验在热线风速仪的流量测量和离子计数器的密度测量中进行，离子计数器可以测量空气中的离子数。旋流增强了射流径向离子迁移率。同时发现离子在射流中的行为受湍流的影响，而不受库仑力和布朗运动的影响。

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.
