Abstract
In this paper, the self-preserving theory of coagulating aerosols is presen ted in a new way: the logarithmic volume (or mass) distribution of an aeros ol undergoing coagulation stays invariant in shape at long times. This is s hown for both the free molecular and continuum regime collision frequency f unctions as well as the constant collision frequency function. In addition, new simple approximate forms are presented for the self-preserving distrib utions, based on numerical solutions to the discrete coagulation equation. (C) 2001 Academic Press.
