摘要：

The impact of a single drop on a liquid film is studied numerically by solving the Navier-Stokes equations for incompressible fluids in three dimensions. The extension dynamics of the splashing lamella is analyzed and compared with theoretical results from the literature. Physically reasonable numerical results for the disintegration of the splashing lamella are obtained by applying disturbances to the liquid film and to the drop. It is shown that for the conditions considered here the Rayleigh instability is a possible driving mechanism for the formation of cusps at the free rim of the splashing lamella.
