Abstract

A numerical model designed to compute timescales for annular liquid film collapse due to surface tension-driven instabilities has been extended to include the effect of surfactant. It is found that surfactant can have stabilizing effect if the surface tension is sufficiently sensitive to surfactant concentration. This stabilizing effect can extend the life of an unstable film by at most a factor of four.
