Abstract. In this paper, a two dimensional numerical model for two phase
ow is presented. For
interface tracking, the FGVT-VOF (Fine Grid Volume Tracking-Volume Of Fluid) method is selected.
For momentum advection, an improved approach is used. In this scheme, a volume tracking step is coupled
with steps of computations for the advection of momentum. A Reynolds stress algebraic equation has been
implemented in the algorithm of turbulent modeling. Standard test cases are used for the veri cation of
interface tracking and hydrodynamic modeling in laminar and turbulent conditions. The test results show
that this methodology can be used in di erent applications of two-phase
ow modeling.
