Evolution of dimensionless and normalized surface area (a,b) and radius of gyration (c,d) for DLCA (Df = 1.79), DLA (Df = 2.25), and BPCA (Df = 2.73) agglomerates consisting initially of 256 primary particles. The results are averaged over 50 different aggregates of each structure and the highlighted areas in (c) represent the range of the standard deviation. If the time is scaled with τA = ηr0(N/2)(0.5-Df/6)/γ, the normalized surface area evolution collapses around a single line (b) and is described well (within 10%) by the KF model (eq 19). (d) The evolution of the radius of gyration scales best with N(0.7–0.18Df). The surface area evolution scales differently than that of the radius of gyration (or moment of inertia).
