| 摘 要： | 研究在垂直布置闭式热虹吸管冷却段内两相流凝结换热特性，讨论了凝结换热系数的预报方法，提出了考虑上升蒸汽速度和液滴夹带现象后的凝结换热系数预报模型，计算表明这两种因素的影响是不容忽视的。

| Abstract: | The condensation heat transfer characteristics of the cooling section in a closed two-phase thermosyphon were investigated for a vertically arranged case,The theoretical methodsfor predicting condensation heat transfer coefficient were discussed.A prediction model wasproposed which could take the effects of upward vapor velocity and entrained droplets intoaccount.Calculations showed that the effects of these two factors were not negligible. |
