| 摘 要： | 以双流体模型为基础,将前人实验得到的相界面浓度,相界面传热系数,气泡上升速度计算式引入双流体模型用来预测冷凝泡状流沿流动方向的含气率分布。模型预测结果与实验数据的比较结果表明,该模型能较好地模拟蒸汽-水冷凝泡状流含气率沿流动方向分布。

| Abstract: | Condensing bubbly flow is numerically simulated using two-fluid modelling approach. Empirical correlation for the interfacial area concentration,interfical heat transfer coefficient and bubble rise velocity is incorporated in the two-fluid model.The Comparison of the experimental data to the present model prediction results show that the model can predict the axial void fraction profile well in steam-water bubbly condensing flow. |
