摘要：The electrostatic charge carried by aerosol particles greatly enhances their deposition in the airways.Electrifications normally occur in aerosol generating process. It has been long suspected that the unipolar chargecarried by the particles may have a significant in the deposition efficiency of the particles in the human respiratory tractduring breathing. Deposition of charged particles in a trachea by their own space charge is investigated analytically,when the number density of the charged particles is large enough so that the potential is a smooth function given byPoisson equation and when the number density of charged particles is small so that only the image force is important.These two approaches have been applied in the mathematical model by using Weibel - symmetric model in the humanrespiratory tract. The mean number density of charged particles in the human air ways at different charge distribution isinvestigated analytically. The results indicates that the electrostatic dispersion can only lead to a small effect on thetrachea deposition, the predominant effect is due to the image force exerted on the particles.
