摘要
与管内两相流空泡份额模型相比,垂直上升横掠水平管束的两相流空泡份额研究成果相对有限。利用垂直上升的气-水两相流横掠水平管束的实验数据,对现有的空泡份额计算模型进行对比分析,并对2种现有模型的拟合公式进行修正。采用其他实验结果对本文重新修正的空泡份额模型进行验证,结果表明:与原始模型相比,修正的空泡份额计算模型给出的空泡份额预测值更好。
Compared with the void fraction models of two-phase flow in tubes, the research on void fraction models for vertically upward two-phase cross-flow in horizontal tube bundle are not enough. With experimental data, the existing void fraction models of vertically upward two-phase cross-flow in horizontal tube bundle are compared. Moreover, two existing void fraction models are modified. The modified void fraction models are validated by some other experimental data. The result shows the modified void fraction models give better prediction than the original models.
