RESUMO

The flow induced by buoyancy forces on an oil inclusion in a cavity full of water is considered. While the density difference effect is counteracted by viscosity and surface tension, an unsteady turbulent flow develops leading to strong interface shearing and stretching with drop extraction and collapse. The final stage is a stratified configuration with the oil on top of water which should be predicted by the numerical simulation.
