Figures & data
FIG. 1. SEM image of the 1 μm pore diameter Nuclepore filter with 350 nm mobility diameter Ag agglomerates deposited.
FIG. 2. Comparison of Nuclepore filter penetrations among NaCl, soot agglomerates, and silver agglomerates at 5 cm s−1 face velocity. The zoom-in images of soot and silver agglomerates are also shown.
FIG. 3. Penetration of Ag particles with different mass-mobility fractal dimensions. Manton model and Spurny-Kim model were in good agreement with data of Dfm = 3.0 and Dfm = 2.1, respectively. Penetrations for Ag particles with Dfm = 2.1, 2.2, 2.6, 2.9, and 3.0 are distinguishable.
FIG. 4. Comparison of experimental and theoretical penetrations at a lower face velocity of 2 cm s−1 for Ag particles with four different mass-mobility fractal dimensions. The model predicted the penetrations of three Ag particles with Dfm = 2.1, 2.3, and 3.0 very well.
FIG. 5. Relationship between the mobility diameter and effective length for Ag particles with different mass-mobility fractal dimensions.
FIG. 6. Mass-mobility fractal dimension as a function of penetration of fractal Ag particles with mobility diameters of 30–150 nm (left) and 180–400 nm (right).
FIG. 7. Effective length as a function of the penetration of fractal Ag particles.
FIG. 8. Comparison of experimental and theoretical penetrations for Ag particles with 2.1 and 3.0 Dfm through 3 μm pore diameter Nuclepore filters at 5 cm s−1 face velocity.
FIG. 9. Suggested operational conditions for particles with mobility diameters of 50–100, 100–300, and 300–1000 nm by different pore diameter Nuclepore filters.
