摘要：

Rupture dynamics of a thin liquid film on a heated substrate has been studied by integrating the fully-coupled nonlinear system of continuity, momentum, and energy equations. The system is solved using finite element method in an Arbitrary-Lagrangian-Eulerian (ALE) frame of reference to update precisely the motion of the moving free-surface. The results of these simulations are compared with those from the long-wave theory. Fully nonlinear process of spontaneous rupture due to thermocapillarity is shown for the first time.
