摘要
We study aerosol growth phenomena in the free-molecular regime. The growth kinetics is clarified by two different approaches, such as the Smoluchowski equation and the cluster-cluster aggregation (CCA) model. The calculated results suggest that the Smoluchowski equation gives a correct description on the aerosol formation. We also study the light scattering intensity on aggregates with non-spherical monomers. The fractal dimension of aggregates does not depend on the microscopic detail of monomers, which confirms the theoretical prediction proposed by restricted hierarchical model.
