Summary

The divergence theorem is applied to the non-linear convective volume integral in the boundary element formulation with the pressure penalty function. Velocity and temperature gradients were thus eliminated, and the complete formulation was written in terms of velocity and temperature. Employing this method, a simulation of surface-tension-driven convective flow in a rectangular cavity with differential heated isothermal lateral walls in a microgravity environment was demonstrated. The effect of different Marangoni, Reynolds and Prandtl numbers on the shape of the free surface, the temperature distribution and the flow fields was also been studied.
