Abstract

Abstract

Transition boiling is a very important thermo-hydraulic phenomenon in the core analysis of pressurized water reactor (PWR), especially in the accident analysis. The accurate simulation of this phenomenon can improve the accuracy of core wall temperature prediction by software. Considering the small range of the transition boiling area and the large variation of the parameters, and the limitation of the test method, there is a lack of recognized and suitable transition boiling model. In order to evaluate the effect of different transition boiling models, six transition boiling models commonly used in the world are compared in this paper. Based on LOCUST, a thermo-hydraulic system analysis software independently developed by China General Nuclear Power Corporation, code development of the six transition boiling models and comparative study of software calculation results and test data were realized. The results show that the Chen relation and the Bjornard-Griffith relation are the best in simulating transition boiling phenomenon, showing good agreement with the experiment data. The results of this study lay the foundation for further exploring the differences and computational effects of various transition boiling heat transfer models, and provide reference for the selection of transition boiling heat transfer models in the development of thermo-hydraulic system analysis software.
