Flows of two-layer falling films are analyzed by an approximate method. Similar to other film flows, there is a non-uniqueness of steady-traveling waves as solutions of the problem. 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 which can be used to model real-life processes, for example, mass transfer of a gas between the layers or gas absorption into a two-layer film.
