【摘要】 本文筛选出5种最具代表性的DNB型圆管CHF机理模型,将原本基于入口条件开发的机理模型转换为当地条件后,植入子通道分析程序ATHAS,基于5×5全长棒束CHF实验数据,研究各模型在棒束通道中的CHF预测性能,筛选出最适用于棒束通道的CHF机理假设,为棒束CHF机理模型的开发提供参考和借鉴。更多还原

【Abstract】 Five most representative DNB type round tube CHF mechanistic model are obtained after evaluation and screening,then these originally mechanistic model based on inlet conditions are converted to local conditions and are coupled with subchannel analysis code ATHAS.Based on 5 x5 rod bundle CHF experimental data,the applicability research of each model for CHF prediction in rod bundle channel is carried out,then the most robust and applicable CHF mechanism for rod bundle channel is obtained.This study provides a reference for the development of CHF mechanistic model in rod bundle channel.更多还原
