Reaction-Advection-Diffusion Systems

These are simulations of a reaction-diffusion system with advection due to a Stokes flow in complex geometries (see the full paper for many more details and simulations in other geometries). After clicking one of the geometries, note that the simulations on the left correspond to a slower fluid flow than those on the right, and hence the pattern selection on the right tends towards tubular or striped patterns, whereas the left tends toward spheres or spots simply moving with the flow.
