Abstract: Aerosol particles contain solid-state and liquid-state particles. In this paper, an EulerLagrange model, a mass transfer model and a chemical conversion model are established. Based on the finite volume method and the SIMPLE algorithm, the liquid-state particles diffusion in air, mass transfer between two phases, and the chemical reactions in particle are simulated. The haracteristics of particle transport and the mass transfer between two phases for three particles with different radii are analyzed numerically, which provides a theoretical basis for finding measures of controlling and removing pollutants.
