Summary
In this project we develop, analyze and implement numerical methods for the
simulation of two-phase incompressible flows with mass transport. The mass
transport of a dissolved species is modeled by a time-dependent convectiondiffusion
equation combined with appropriate coupling conditions at the interface.
The solution of this equation is in general discontinuous across the
unkown interface between the two phases and in our applications this problem
is often convection-dominated. This causes severe numerical difficulties. We
plan to develop new stable and efficient finite element discretization methods
for this transport equation. Both a rigorous error analysis and the application
of these methods will be investigated. The methods will be implemented in
a software package (DROPS) that is available in our group. The numerical
simulation of fluid dynamics and mass transport with the DROPS package
will be validated in collaboration with a partner from an experimental project
on Taylor flows in mini-channels.
