A two-dimensional front-tracking method is developed for handling complex shape interfaces satisfying the volume conservation. In order to validate the proposed front-tracking method, a complete convergence study is carried out on several
analytical test cases for which the interface is widely stretched and deformed. Comparisons to different existing approaches show that our front-tracking method is second
order accurate in space with lower errors than existing interface tracking techniques of
the literature.
We also propose an original marker advection method which takes into account the
jump relations valid at interface in order to deal with the contrast of physical properties
encountered in two-phase flow simulations. The conservative front-tracking method
computed in this work is shown to be able to describe interfaces with high accuracy
even for poorly resolved Eulerian grids.
