In the present work, different closure relations in the one-dimensional Two-Fluid Model were
investigated in order to assess the effect on the numerical simulation of vertical annular …

The optimal design of two-phase flow pipes depends on various variables. Pressure drop
and liquid hold-up are essential parameters in the appropriate design of pipes. These …

Recent advances on the modeling of two-phase flows in pipes have shown that the accurate
modeling of Two-Fluid equations allow the dynamic simulation of various regimes within a …

The purpose of the present study is to compare the well-posedness criteria of the free-
pressure two-fluid model, single-pressure two-fluid model, and two-pressure two-fluid model …
