Abstract
The effect of gravity on the dynamics of non-isothermic ultra-thin two-layer films is studied. The problem is considered in a longwave approximation. Periodic boundary conditions have been applied on the boundaries of the computational region. The problem is solved by means of a linear stability theory and nonlinear simulations. Nonlinear wavy regimes, including two-dimensional and three-dimensional traveling waves, as well as different kinds of three-dimensional standing waves, have been studied.
