Summary:In this study, in order to clarify the heat transfer characteristics of the subcooled pool boiling and to discuss its mechanism, a boiling and condensation model for numerical simulation on subcooled boiling phenomenon has been developed. The developed boiling and condensation model consists of the improved phase-change model and the relaxation time based on the quasi-thermal equilibrium hypothesis. Three dimensional numerical simulations based on the MARS (Multi-interface Advection and Reconstruction Solver) with the developed boiling and condensation model have been conducted for a nucleated bubble growth process in the subcooled pool boiling. The numerical simulation results showed in good agreement with the experimental observations. Therefore, the developed boiling and condensation model is validated for the prediction of the subcooled pool boiling phenomena.
