| Abstract | ||||
| The objective of this paper is to make review and comparison between the methodologies used for modeling condensation with non-condensable, in two-phase flows channel. The important state-of-the art numerical algorithms for the solution of multi-phase conservation equations are reviewed. The methodology for modeling condensation in these algorithms is based on the stagnant film theory. The methodology used in RELAP5/MOD3 that was the most accurate model is rigorously treats the coupling between the heat and mass transfer process, and gas-liquid interphase without iteration.
