Attracting wave regimes for two layer falling films.

We analyze flows of two-layer falling films by using approximate long-wave model. There is a non-uniqueness of steady-traveling wave regimes as solutions of the problem which is utilised in mass transfer technologies. To select the wave regimes developing in two-layer films, systematic transient computations have been carried out to create a map of the attracting wave regimes, so-called dominating waves, which can be used to model real-life processes.
