| Résumé : | This paper deals with the nonlinear evolution of a thin liquid film in contact with a hot rigid plate. The liquid phase is separated from its own vapour by a deformable interface. Various mechanisms affect the stability of the film and govern its shape. Among them, we focus on the sur- face tension and its variation with temperature, the evaporation and the resulting vapour recoil pressure resulting from momentum conservation at the interface, the disjoining pressure resulting from molecular interactions with the sub- strate, the temperature discontinuity between vapour and liquid at the interface and the variation of the saturation temperature due to the disjoining pressure and the interfa- cial curvature. We show how the contact angle and the heat flux vary with some of these effects. |
