Paper Abstract

This paper is devoted to the numerical simulation of thermocapillary flows occuring in laser surface treatment. A two dimensionnal rectangular cavity is used to model the molten pool which occurs when a laser beam impinges a material. The simulated free surface, considered flat or deformable, is subjected to a sinusoidal temperature distribution. Motion equations are solved by a finite element method. Effects of dimensionless parameters on the convection in the melt are shown.
