Abstract:
According to the in-vessel retention(IVR) mitigation and the heat transfer characteristics,two theoretical models for predicting the critical heat flux(CHF),the interfacial lift-off theoretical model and the theoretical model considering the hydrodynamic behavior of the vapor-liquid interface of a bubble,are modified,respectively,and a general CHF model is developed to analyze the lower head CHF.The results indicate that the CHF model could well predict the experimental data on large scale curved surface.
