Figure 3.
Temporal evolution of (a) dimensionless A/A0 and (b) normalized surface area A′ by the present work (lines) and by Yadha and Helble21 (symbols) for pairs of particles with size ratios r1,0/r2,0 = 1–6. If the time is scaled with the radius of the small particle r(t), the evolution of A′ collapses around a single line described well by an exponential model (double-dot broken line) with the proposed fusion time τA = ηr(t)/γ. The colors of the inset particles correspond to their large (blue) and small (red) curvature (= 1/radius).
