Abstract: The problem of 3D motion of charged particles under the action of space charge and image electrostatic forces inside a grounded sphere is solved using the Lagrangian method. The efficiency of particle deposition on the sphere is studied for various initial particle concentrations. The numerical results are compared with the known analytical solutions. The relative contribution of space charge and image forces to particle deposition is discussed.

Keywords: charged aerosol particles, deposition, image force, space charge force.
