Inertial capture of aerosol particles by swarms of accelarating spheres

The deposition of aerosol particles on swarms of accelerating spherical glass beads was studied over a range of aerosol particle sizes and air velocities, and two glass bead sizes. The results were interpreted by a theoretical model which was based on equations valid for inertial impaction and interception of spheres on single, stationary spheres, and which included an empirical factor dependent on the volumetric concentration of the collection particles.
