Coagulation of Particles

Coagulation of Many Sizes

Consider an aerosol, which initially consists of particles of different sizes. The concentration of the k^th size particle then satisfies the following equation:

(15)

where the first term on the right hand side is the generation rate of the kth particle by combination and the second term is the loss of kth particle due to coalescence. Here,  shown in Figure 2 and is given by

(16)

The corresponding values of  are listed in Table 1 (next page).
