Abstract
A discrete-sectional model is presented that can simulate the simulate the aerosol evolution associated with fast chemical reactions. The mechanisms of coagulation, evaporation, and chemical reactions are treated in this model. Test calculations were performed to examine the sensitivity of the resulting number concentration and size distribution to the breakpoint between the discrete and the sectional regime, k, and the number of sections, M, used. The numerical diffusion problem in this model due to the condensational growth was also examined. Simulations of refractory particle formation and growth in aerosol reactors by gas-phase chemical reactions were in good agreement with previous experimental observations.
