Abstract
The behavior of bipolarly charged aerosol particles undergoing electrostatic coagulation was studied from the theoretical and experimental points of view. The population balance equation for the behavior of the charged particles which includes the simultaneous effects of electrostatic coagulation, electrostatic diffusion and Brownian coagulation was numerically solved for aerosol particles having various initial charge distributions. As a result, the time-dependent changes in particle number concentration and charge distribution under the effects of electrostatic coagulation, electrostatic diffusion and Brownian coagulation were evaluated for various cases. Some of these results were compared with the experimental results obtained by a visual method, and were found to be in good agreement with them.
