Direct simulations of droplets impacting oil slicks

2D and 3D computations of water droplets impacting oil slicks at the surface of water have been performed for different conditions of Weber number, Reynolds number, and oil layer thickness. These calculations have improved the understanding of high energy impacts, and it has also shown the requirements in terms of local mesh to capture the mechanisms in play, both in 2D and 3D. Comparisons with existing experiments have shown a reliable agreement regarding the time evolution of the cavity and crown created by the splash. The statistics about droplets and bubbles generated by the impact can be also partially reproduced, depending on the mesh resolution.
