An accurate prediction of void generation and phase distribution on heat transfer under sub-cooled boiling regime is required in many industrial and laboratory applications. In this paper a onedimensional code was implemented in order to study the mass and heat transfer amount phases during high heat transfer in water-steam systems. To obtain a well-postulated model, in a first step it was implemented a one-dimensional Eulerian-Eulerian two-fluid model. Attention was focused on the interfacial momentum exchange between phases caused by drag efforts. The two-fluid model implemented was generated following the solvers and libraries implemented on CFD OpenFOAMR code due to its full access, easy solver generation and modification. Finally, a mechanistic model from literature to predict sub-cooled boiling and bulk condensation is implemented and assessed with experimental data. This paper presents the constitutive relations implemented and highlighting the mechanistic model for mass exchange prediction.R code due to its full access, easy solver generation and modification.
