| Abstract: |
|---|
| The role of surfactants in stabilizing the formation of
bubbles in foams is studied using a phase-field model The analysis is
centered on a van der Walls-Cahn-Hilliard-type energy with an added
term accounting for the interplay between the presence of a surfactant
density and the creation of interfaces. In particular, it is concluded
that the surfactant segregates to the interfaces, and that the
prescription of the distribution of surfactant will dictate the locus
of interfaces, what is in agreement with experimentation. |
