Figure 2

Cartoon (a) of axial-azimuthal (y, z) cross-section with streamlines of recirculation flow in a DIB pair due to shearing flow at the top of the droplets from the non-polar phase (hexadecane) with the velocity flow profile uy (x, z). Micrograph (b) of a ‘minimum intensity Z-projection’ (processed on ImageJ) from a (top view) image sequence of particle motion in a double lobed, symmetric vortex pair within a DIB. Cartoon (c) of the streamlines of the top half of the DIB pair on the x-y plane in (b), which shows the flow direction and recirculation flow around the side of the droplets.
