Pigment dispersal across variable anisotropic flow fields.
(a) Four Hele-Shaw cell states with spatially-varied outlet boundary conditions. (b) Estimated (idealized) steady-state potential flow field from cell configurations in a. (c) Overlaid time-series images demonstrating anisotropic droplet growth over time. (d) Final droplet configuration from c with overlaid gradient vector field from b.
