| 摘 要： | 本文是对管内流动的临界热流进行试验研究和理论分析.从沸腾机理分析和应用两相流的相似原理进行处理,我们推导了表达临界热流计算的准则方程.用6种不同的冷却剂,355个实验数据进行修正处理求得了常数A和指数h,m,n的数值.引入一个考虑冷却套缝隙高度变化影响的无因次修正项,上述方程成为计算管内流动临界热流的通用方程

| Abstract: | This paper is experimentally and theoritically to investigate the critical heat flux of flow in pipes. From the analysis of the boiling mechanism and processing by means of the analogy principle of two-phase flow, we have been derived a criterion equation to express critical heat flux. Correlated with 6 different coolant, 355 experimental data,constant A and exponents K,m,n are obtained. With a dimensionless correction, term to calculate the effect on the variating sloted height of the cooling jacket, the previous equation will be a general equation to calculate the critical heat flux of flow in pipes. |
