This study focuses on the clarification of the heat transfer characteristics of the subcooled pool boiling, the discussion on its mechanism, and the establishment of a numerical boiling and condensation model for numerical simulation on subcooled pool boiling phenomena. In this paper, the three dimensional numerical simulations based on the MARS (Multi-interface Advection and Reconstruction Solver) with an improved phase-change model combined with a relaxation time based on the quasi-thermal equilibrium state have been conducted for the subcooled pool boiling, especially subjects to the bubble growth and the bubble condensation and extinction processes, and then the numerical results are compared with the experimental results and the existing analytical models.
