Application of VOF and SPH to solve problems with a developed free surface

This article discusses methods for simulation of flows with free surfaces within the Euler (Volume of fluid — VOF ) and Lagrangian (Smoothed Particle Hydrodynamics — SPH) description. On the example of problems of interaction between the flow of an incompressible fluid and obstacles, we evaluate the possibility of using the methods to describe the developed free surface and the process of dropping. Numerical results obtained by the methods VOF and SPH are compared with experimental data.
