| 摘 要： | 采用管内汽液均相流模型理论式和实验公式相比较的方法得到了计算竖直管路内自然循环流动沸腾临界热通量的半理论半经验型公式，弥补了理论式不能适用于短粗管路的不足，使用此公式与作者的实验及其他文献的实验结果进行了比较，两者十分吻合。

| Abstract: | An analytical and experimental study is made of the critical heat flux of natural convection boiling in vertical shorts channels and shorts tubes. The generalized approximate formulas are founded by the adopted analysis of a mixed flow model combined with experimental collection. The formulas remedy the defects of pure analytical formulas that can't apply to the case of shorts channels and shorts tubes and agree well with the CHF experimental data. |

| Keywords: | heat flux boiling mixed flow narrow space boiling phase change |
