Numerical Model of Post-DNB Transition Boiling Heat Transfer

In this paper a physical model for the transition boiling heat transfer is proposed.The corre-sponding mathematical descriptions are given in detail and the heat transfer characteristics of post-DNB tran-sition boiling is analyzed.The numerical model of post-DNB transition boiling heat transfer is obtained as the empirical value of the coefficient is determined by the experimental data.The numerical model is compared with the experimental data of different parameters and other numerical models,and the statistical deviations are calculated.The calculating results of the numerical model in this paper show good agreement with the experimental data,and the numerical model in this paper is with good applicability compared with other nu-merical models.
