Abstract

Transport and deposition of charged particles from a turbulent flow within a cylindrical precipitator are analyzed theoretically. Particle collection efficiency is calculated for different diffusivity models. The effect of particle inertial properties upon the collection rate is studied. It is shown that the Deutsch formula for particle efficiency is valid for moderate values of the applied electrostatic field. The performances of parallel plate and cylindrical precipitators are compared on the basis of the calculated collection efficiencies. The effect of the dielectrophoretic capture mechanism upon the particle collection rate is evaluated.
