Abstract

A theoretical model for the removal of aerosol particles by falling columnar ice crystals is compared to the model results for the removal of aerosol particles by falling planar ice crystals. These results incorporate gravitational, inertial, electrostatic, thermophoretic, diffusiophoretic, and Brownian diffusion mechanisms. Scavenging rates for columnar and planar ice crystals are computed for aerosol particles ranging from 0.001 to 10 μm in radius. The results show that planar ice crystals have greater collection efficiencies than the columnar ice crystals.
