In this paper, charging kinetics of polydisperse aerosol particles in a corona field of a coaxial electrode system is numerically analyzed for a logarithmic normal distribution of aerosol particle size. The particle charging and the particle current are calculated by using a charging model considering ion concentration and particle mobility. Particle charging profiles under varying ion density and electrical field intensity distributions of the charging chamber were revealed. A low charging profile in the transition region of bipolar corona field was demonstrated in the simulation results.
► A numerical analysis of aerosol particles charging process is proposed. ► Particle charging profiles under a varying ion density are investigated. ► A low charging profile occurring in a bipolar corona field is demonstrated. ► Aerosol particle charging stability in a charging chamber is discussed.
