Unipolar charging of aerosol particles in alternating electric field

Electrostatic charging of fine aerosol particles in an ionic current and alternating electric field enables charge imparted to the particle to be close to the Pauthenier limit. The charging process was simulated numerically and compared with the experimental results. The numerical simulation takes into account the gravitational, drag, inertial and electrohydrodynamic forces influencing the particle motion in the alternating electric field charger. The increase in the charge on the particle during its flow through the charger and the effect of the frequency of the electric field on the charging process were also determined.
