Fig. 4: Extensile two-core emulsion with homeotropic anchoring: Rotating regime.
From: Topology controls flow patterns in active double emulsions
a, b Front view of typical structure of the director field (headless vectors), velocity field and disclination lines during time evolution of a two-core emulsion in the rotating regime (panels correspond to t = 4 × 105 and t = 4.5 × 105 respectively), for ζ = 0.02. The loop disclination consists of two regions of +1/2 defect profiles (yellow segments), which smoothly convert into regions of two −1/2 profiles coasting the cores (purple segments) by means of intermediate twist defects (green segments). c Velocity field in the longitudinal plane for the same configuration shown in (b). Panel (d) shows the director and the velocity field near the +1/2 and −1/2 defect profiles. Panels (e, f) and (i, j) refer to the case ζ = 0.04 (t = 4 × 105 and t = 4.5 × 105, t = 5 × 105 and t = 5.5 × 105 respectively). Panels (g) and (k) show the side view of the velocity field for the same configuration in panels (e) and (i). Panels (h) and (l) show the director field (black headless vectors) and the velocity field around the disclination line for the same configurations.
