ABSTRACT
When aerosols are formed by gas phase chemistry or nucleation, large concentrations of small panicles are formed which grow by agglomeration and further condensation. In certain cases, plasma and EB reactions, ion-molecule reactions may play an important role. However, the aerosol forming in the reaction constitutes a significant sink.
This paper describes the magnitude of the sink. It is shown that for electrically neutral aerosols, there is a substantial enhancement of ion removal for smaller particles. We examine the effect of size distribution (both the variance of the distribution and the specific parameter representation) and the specific charging theory. The diffusional charging theories examined were the minimum flux theory and the Fuchs theory. Log normal and log Beta distributions having the same variance and mean were compared. Changes in the calculation for small ion concentrations were considered.
