The various approaches used for modelling interfacial mass generation in two-phase flow are reviewed. The mass generation problem is strongly related to the questions of interfacial heat transfer and to the determination of the interfacial area. The available literature is discussed and a classification is made according to the nature of the heat transfer regimes or mechanisms (growth of bubbles, evaporation of droplets, post-dryout heat transfer, subcooled boiling, etc.) as well as according to the nature of the model used (mechanistic models, relaxation, profile-fit and empirical methods). Whenever possible, the discussion is directed toward the definition of the closure laws needed for the modern two-fluid thermal-hydraulics codes.
