摘要
以低压过冷流动沸腾的临界热流密度 (CHF)的实验数据为基础 ,对典型的CHF计算公式、模型及 95CHF表作了评价。所用数据共 2 37点 ,范围如下 :压力 0 1 3~ 1 92MPa;速度 1 4 7~2 2 32m/s;出口过冷度 6 2~ 1 0 8 7K ;加热长度 2 5 5~ 40 0mm ;管径 5 1 7~ 1 6 0mm。
Based on the 237 points of experimental data obtained under pressure of 0.13~1.92 MPa, velocity of 1.47~22.32 m/s,subcooling of 6.2~108.7 K, heated length of 255~400 mm and tube diameter of 5.17~16.0 mm, an evaluation of the typical CHF correlaitons, models and the 95 CHF Look up Table was carried out. It was found that the Gambill correlation and the Celata Model gave better prediction, and the 95 CHF Look up Table overestimates the effect of the pressure while underestimates the strong effect of the subcooling.
