Abstract

The linear stability of two−layer film flow on an inclined plane and on the surface of a rotating disk is examined. Two types of instability are investigated. One corresponds to the existence of the boundary between liquids and another type is similar to that examined for one−layer films and it is formed due to the free surface.
