摘要： 建立了电站冷凝器壳侧气液两相流动和传热的两流体数值模型，基于分布阻力方法建立气液两相的控制方程级，对N11220—1型冷凝器进行了数值分析，计算表明液相对冷颖器总体性能的影响不显著。结果与试验数据和单相模型的结果进行了比较，两流体模型计算的相对热流密度与试验值吻合良好，精度比单相模型有所改进。

Abstract: A two-fluid numerical model for predicting two-phase fluid flow and heat transfer behavior in the shell-side of large power plant condensers is developed and applied to a 200 MW power plant condenser. With this method, the conservation equations for both vapor-phase and liquid-phase are established based on the distributed resistance method. The predicted results show that there is no obvious effect of liquid phase on the overall performance of the power plant condenser due to the existence of drainage baffles. The predicted results agree well with the experimental data, and show a little improvement over the results obtained using the single-phase model.
