Abstract

The paper presents a numerical algorithm for simulating the trajectories of charged dust particles moving horizontally in the vicinity of free falling, oppositely charged liquid droplets. The trajectories are calculated in three-dimensional space which shows limiting collision trajectories of the particles and the precipitation space to be determined. The air drag, electrical and gravitational forces are taken into account. A number of different models for the air flow around a spherical droplet are compared. The algorithm is used to determine the collection efficiency, according to a newly proposed definition, for a single charged spherical collector
