Abstract

In acid rain formation there are the two main mass transfer processes (scavenging of atmospheric pollutants). The one is the rainout and the other is the washout. The purpose of this study is to clear the indistinct effects of the concurrent washout of pollutant gases SOg(g) andHNOs(g) on the nonsteady acidification process of rain- drops. A simple lumped parameter model, which is based on the physico chemical consideration of the mass transfer and the chemical reaction, has been constructed and the dynamics of raindrop acidification process has been simulated numerically with u
