Abstract:
We consider a ow problem with two di erent immiscible incompressible new- tonian phases ( uid- uid or uid-gas). A standard model for this consists of the Navier-Stokes equations with a viscosity and density that are discontinuous across the interface and with a localized force at the interface that describes surface tension e ects. This uid dynamics model can be coupled with a model for mass transport between the phases and a model for transport of surfac- tants on the interface. We discuss why the ecient and accurate numerical simulation of such models is a very challenging problem. Two topics, namely the discretization of the mass transport equation and the discretization of the surfactant equation on the evolving interface will be treated in more detail.
