Preserving the Volume of Fluid Using Multi-phase Flow Approach

Le résumé fourni par la source

Methods to animate multiphase fluids are rarely researched, although such phenomena are common in our daily lives. The main focus of this research is to develop a suitable method to create realistic animation of multiphase flows, i.e. flow of fluid mixtures. Our method is based on Navier-Stokes equations, a set of physical equations that describe motion of fluid. A Marker-and-Cell (MAC) grid is used to solve the equations on discrete computational domain. To simulate several fluids, we propose the modification of Volume-of-Fluid (VOF) representation of fluid and integrate it into the multiphase-fluid approach. A mixture of fluids is treated as a single fluid having variable density and viscosity. This scheme allows two or more fluids having different densities and viscosities to be simulated simultaneously.
