a Time-lapse sequence of the system configuration for Φ = 0.22 (Nd = 50) and A = 864 (ζ = 0.06), resulting in a fully separated state. b, c Color maps of the hydrodynamic pressure Ph (panel b) and the active force (panel c) at time t = 2 × 102 τ. d, e Temporal evolution of the structure factor of the concentration field (panel d) and the kinetic energy spectrum (panel e). f Characteristic cluster size ℓϕ and flow structure size ℓv—derived as the inverse of the first moment of their respective structure factors—plotted versus time. g PDF of the droplet velocity component vx. The color scales in panels (f, g) correspond to those used in panels (d, e).
