Thermocapillary convection in a three-layer system with the temperature gradient directed along the interfaces
Comptes Rendus. Mécanique, Volume 333 (2005) no. 4, pp. 311-318.

The paper presents numerical simulations of the Marangoni–Bénard convection in a real symmetric three-layer system. The temperature gradient is directed along the interfaces. Nonlinear regimes of steady and oscillatory convective flows are investigated by means of the finite-difference method. Transitions between the motions with different spatial structures are studied.

Ce travail présente les simulations numériques de la convection de Marangoni–Bénard dans un système réel symétrique à trois couches. Le gradient de température est dirigé le long des interfaces. Les régimes non-linéaires des écoulements convectifs stationnaires et oscillatoires sont étudiés par la méthode des différences finies. Les transitions entre les mouvements à structure spatiale différente sont également étudiées.
