“…The particle number concentration N (M 0 , the zero-order moment of particle size distribution), particle volume (mass) concentration M (M 1 , the first-order moment of particle size distribution), and the particle size distribution function, which is expressed in terms of P k (the probability of obtaining a cluster obtaining k primary particles), are calculated and compared with the analytical solution (Zhao et al 2007). To this end, the mean standard deviations σ ξ (t) of these parameters ξ (N , M or P k ), obtained by comparison with the analytical solution, are calculated according to:…”
