Nonlinear waves in a multilayer system
Comptes Rendus. Mécanique, Volume 337 (2009) no. 2, pp. 75-83.

The joint action of buoyant and thermocapillary mechanisms of instability in a multilayer system, is investigated. The nonlinear convective regimes are studied by the finite difference method. The periodic boundary conditions on the lateral boundaries, are considered. It is found that the competition of both mechanisms of instability may lead to the appearance of a buoyant–thermocapillary traveling wave and a modulated traveling wave.
