Kas-Danouche, Said A mathematical model for core-annular fluids with surfactants. (English) Zbl 1147.76020 Bol. Asoc. Mat. Venez. 14, No. 1-2, 27-39 (2007). Summary: We investigate the influence of surfactants in core-annular fluids without basic flow. The surfactant is considered insoluble in both film and core fluids. We derive a complete problem and obtain an asymptotic solution which satisfies a system of two coupled nonlinear partial differential equations. One describing the evolution of the interface and the other, the evolution of surfactant concentration throughout the interface.
