center of mass of each transient shape has been shifted by a uniform axial distance, the displayed position does not reflect any differences in migration velocity. Both simulations shown in Figure 6.3.18 are initiated with a spherical shape. Breakup occurs through the re-entrant cavity mechanism reported by Olbricht & Kung [50] for clean drops. The apparently faster rate of growth of the penetrating jet in Figure 6.3.18(b) suggests that the presence of surfactants has a destabilizing influence.
