Figure 3.9: Initial and steady-state average size distributions of spray in CFSTR model of coalescence.<br />

Surface area S, and total mass drop dramatically <strong>from</strong> the input spray. Ecoal is the probability of coalescence<br />

given a collision (Ecoal = 1 implies every collision results in coalescence). S is the average surface of<br />

the spray per unit volume of contactor in m 2 /m 3 . Input spray is the “average” distribution <strong>from</strong> Figure 3.6<br />

(same as previous two figures) and “full-scale” spray density <strong>from</strong> Figure 3.7 (same as previous figure).<br />
