Abstract

The filtration of solid aerosol particles produces a decrease in filter penetration and an increase in filter resistance because of the accumulation of deposited material. Functions are derived for the effects of particle accumulation on filter penetration and resistance. A new aerosol tunnel is described which provides a uniform field of particle and fluid flow for extended periods. Data are presented on the effects of accumulation of 1.3-micron polystyrene particles on the performance of filter mats tested in the aerosol tunnel. A quantitative microscopic study of accumulation of 1.3-micron particles on single isolated 10-micron glass fibers is described. Photographs of deposit structure and measurements of aggregate size are included.
