The nuclear reactor research community is interested in charged aerosol dynamics in a confined environment. Various aerosol charging theories described for bipolar and unipolar ion field exposures are reviewed using experimental measurements with PSL aerosols and ELPI. The (n+/n-) ratio of bipolar ions marginally increases as more negative ions get attached to aerosols. The charge level obtained from generation reduces under bipolar ion field but increases enormously under unipolar ion field. The charged aerosol concentration decay is not changed significantly under bipolar ion field when compared to the baseline condition but enhanced by more than one order under unipolar ion field.

双极和单极离子场下聚苯乙烯乳胶气溶胶的充电和动力学——ELPI测量及与充电理论的比较
核反应堆研究界对密闭环境中的带电气溶胶动力学很感兴趣。使用 PSL 气溶胶和 ELPI 的实验测量来回顾针对双极和单极离子场暴露描述的各种气溶胶充电理论。随着更多的负离子附着在气溶胶上,双极离子的 (n+/n-) 比率略微增加。产生的电荷水平在双极离子场下减少,但在单极离子场下大幅度增加。与基线条件相比,双极离子场下的带电气溶胶浓度衰减没有显着变化,但在单极离子场下增加了一个数量级以上。
