Bubbles

Two immiscible fluids are simulated without (left) and with
(middle) surfactants
added. Without surfactants the two bubbles quickly coalesce, but
with surfactants they bounce off. The concentration of surfactants
is the largest at the interface, as is investigated in the
rightmost animation.
The modeling and the numerical method is described
in S. Engblom, M. Do-Quang, G. Amberg, and A-K. Tornberg: On
diffuse interface modeling and simulation of surfactants in
two-phase fluid flow, in Commun. Comput. Phys.
