摘要
重力热管作为一种高效的传热元件已在众多领域得到广泛应用,然而其性能受到传热极限的制约.本文建立二维稳态数学模型分析垂直放置的重力热管冷凝段的携带极限,并与其它研究者的实验数据和计算结果进行比较,分析了两种气液界面剪切力计算方法的适用性。
The two-phase closed thermosyphon (TPCT), which is an effective heat transfer unit, has been widely applied in many fields. Its heat transfer performance is restricted by the heat transfer limit. A two-dimensional model was developed to investigate the flooding limit in condenser of a vertical TPCT. The calculation results were compared with the reported experimental data and the other calculation. Two types of method for calculating the interfacial shear stress were discussed.
