English Abstract: In order to understand the characteristics of free surface evolution in thermo-solutocapillary convection formation, a set of two-dimensional numerical simulations is conducted using level set method for thermo-solutocapillary convection in a rectangular cavity. The opposing thermocapillary effects equivalent to solutocapillary effects is considered. The computational results show that, the vortices first appear at the right side and travel to the left side gradually, and the flow field forms two comparable size vortices at final state. Meanwhile, the free surface deformation first increases and then decreases, and finally keeps a small constant deformation. Moreover, the effects of Marangoni number, Lewis number, Capillary number, aspect ratio and Prandtl number on the free surface evolution are analyzed.
