Process of Deposition and Growth of Aerosol Particles on Nuclepore Filters

Abstract

The effects of deposited particles on performance of the Nuclepore filter were studied theoretically and experimentally under conditions of the collection mechanisms of inertia and interception. A capillary filter model given by Pich was chosen as a model of the Nuclepore filter. The process of particle deposition was calculated by simulating the motion of particles using the Monte Carlo simulation method.
The simulation results were used to estimate the collection efficiency and to find the morphology of deposited particles. A comparison between the simulation and experimental results was presented. The theoretically predicted collection efficiency was in agreement with experiments for the collection mechanism of inertia predominance.
