Abstract
A multicomponent modal aerosol model suitable for two- and three-dimensional applications is introduced. Besides the moments of the size distribution, the model yields information on the time evolution of the mode-average particle composition. The model is applied to a laminar flow aerosol reactor (LFAR) problem, and the results are compared with the experiments by Nguyen et al. (1987) J. Colloid Interface Sci. 119, 491–504 and with those of the previously published models. The influence of different model parameters is examined. The wall temperature profile is shown to be of crucial importance for LFAR simulations and experiments. For the classical nucleation rate as well as for the modified classical nucleation rate by Girshick et al. (1990) Aerosol Sci. Technol. 13, 465–477, suitable correction factors, which give good agreement between simulation and experimental data over a wide range of experimental parameters are presented.
