摘要
基于PHOENICS操作平台,采用具有分布阻力和分布质量汇的多孔介质物理概念,建立凝汽器汽侧流场的三维模型,并以某电厂300MW凝汽器为实例,将凝汽器壳侧复杂的混合物流动过程经过简化后计算模拟出来,计算结果与实际情况基本吻合,并在此基础上进行了理论分析,得出一些有参考价值的结论。
Based on the PHOENICS software, with the help of a conceived porous medium, which allows for a distributed blocking effect and has a distributed mass, a 3-dimensional steam flow field model of a condenser is set up and, taking a certain power plant's 300 MW steam turbine's condenser as an example, the flow process of the complicated mixture of matter is being numerically simulated. Results of calculation almost concur with actual conditions. Accordingly, some referential conclusions are obtained by theoretical analysis.
