... Abstract Study on the droplet entrainment in annular two-phase flow has attracted many researchers in connection with the liquid film dryout in the annular two-phase flow. However, the knowledge on the entrainment due to nucleate boiling is still insufficient to predict the droplet entrainment...

... Abstract Dryout and post-dryout heat transfer experiments in a tight three-rod bundle with spacer grids are carried out at Shanghai Jiao Tong University. The test section is made up of three heated rods with an outer diameter of 15 mm and three unheated components. The pitch-to-diameter ratio...

... 05 03 2009 For the purpose of predicting CHF for a wide range in quality, we developed the analytical CHF prediction method. Two-phase flow analysis code based on multi-fluid model was developed and, by using typical dryout model and DNB model, CHF predictions for a wide range...

.... are investigated in detail. The critical heat flux are also predicted in vertical upward round tube according to the theory that the dryout in vertical annular flow emerges at the point where the film is depleted due to the integrating result of entrainment, deposition and evaporation. The influence of mass flux...
