DEPOSITION OF AEROSOL-PARTICLES ON A CHARGED SPHERICAL COLLECTOR

A numerical model for determining the trajectories of a spherical aero sol particle in the vicinity of a spherical collector is presented. Th e Coulomb, image, Stokes, inertial and gravitational forces acting upo n the particle and the collector are taken into consideration in the e quations of motion. The system of equations is solved in 3-D space. Th e flow field in the vicinity of the collector is determined by numeric al solution of the Navier-Stokes equations. The examples of aerosol pa rticles' trajectories are presented for a few values of the Coulomb an d Reynolds numbers.
