Numerical simulation of free surface flows, with multiple liquid phases

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We present a numerical framework for the simulation of multiphase flows with free surfaces, thus considering N incompressible liquid phases together with a vacuum. An Eulerian model is favored to track the liquid phases, based on several characteristic functions. The numerical algorithm relies on a time splitting strategy, together with a two-grid discretization method. Numerical experiments are presented for impulse waves, and for rigid bodies falling into an incompressible liquid.
