Particle size curve

The detailed size dependence at the Fermi level is shown in Figure 12 [171]. Although the Fermi cutoff is already detectable even at the smallest particle size (curve (c)), there is change near the Fermi level in the 0-0.6 eV BE... 

Figure 8B shows the characteristic theoretical and practical collection efficiency curve. The x-axis may be plotted as particle diameter, in which case a series of curves at ever-decreasing sizes representing different stages of the impactor would exist. Converting the data to the square root of Stokes number overlays each of the particle size curves. The characteristic Stokes number for circular jets is 0.22.

Figure 4. Enrichment factors (relative to Sc) vs. particle size curves for aerosols collected up- and downstream of the flue-gas desulfurization system show considerable concentration enhancement in the submicrometer size region.

Figure 5. Enrichment factor vs. particle size curves for Cr and Mn show chemical enhancement of both large and smaller particles.

The efficiency predicted by Eq. 8.15 is only a rough estimate the equation estimates a shape in the efficiency-versus-particle-size curve that is different from what is actually observed. There are a number of factors not considered in this elementary derivation. First, laminar flow is assumed, but turbulent flow is often observed in practice. The effect of turbulence will be to move particles away from the cyclone walls or resuspend deposited ones. Hence, turbulence will decrease cyclone efficiency. Second, the width of the cyclone inlet is not as important a parameter as overall cyclone diameter, since it is the width of an element of gas within the cyclone that determines particle deposi-...

That conformation to self-similarity is excellent is evidenced by a plot of the arc length versus particle size curve shown in Figure 6.1.2. This plot was obtained by assembling different segments of the curve for different cumulative volume fractions by fitting a smooth quadratic curve to In t versus In x from all of the data at hand.
