摘要

在圆形管内

对极限干度区的临界热流密度（CHF）进行了理论研究。通过对Whalley模型进行数值求解

并分析其在极限干度流动条件下的适应性

得到了适用于圆形管内环状流临界热流密度的本构方程。数值预测结果通过与几个主要的CHF预测模型相比较表明该本构方程对极限干度区CHF的预测精度较高。

Abstract

Based on theoretical investigation of critical heat flux of annular flow in limiting quality regime(LQR)

the Whalley model is solved numerically and the adaptability of the model in LQR is analyzed.Furthermore

a physi-cal model of critical heat flux used to the round flow tube is developed and compared with some other major physical models.Prediction results show that the physical model works very well because of its relative high accuracy.
