Particle Deposition in a Charged Aerosol Flowing Through a Conducting Tube

Abstract

A mathematical analysis is presented for charged aerosol flowing in an infinitely long, cylindrical, conducting tube. The aerosol is assumed to move in “plug” flow and to be dilute, unipolar, and of uniform size and charge. Repulsion due to the particle space charge is the only mode of deposition considered. Ignoring particle inertia, numerical results indicate that Wilson’s equation yields a good approximation for concentration as a function of axial distance. Solutions obtained when particle mass is considered indicate the importance of radial inertia.
