Fig. 6: Speed of the cores.
From: The vortex-driven dynamics of droplets within droplets
Time evolution of the y and z components of the velocity of center of mass of the two cores computed with respect to that of the external droplet. The inset highlights the position of the inner drops at the points of inversion of motion. Red and blue arrows indicate their direction of motion. Snaphots are taken at t = 3.6 × 105 (a) and t = 4.94 × 105 (b) timesteps.
