摘要
核电汽轮机分为全速和半速汽轮机,由于转速的不同会导致两种汽轮机运行时各种参数的差异,所以合理选择汽轮机转速也是非常必要的。用CFX作为工具,通过模拟汽轮机内部的流动,来对比全速和半速汽轮机湿度、马赫数和压力的分布,分析了不同转速下它们之间的相互影响。模拟结果可为核电汽轮机的选型提供参考。
Nuclear power turbine can be classified full-speed turbine and half-speed turbine, which has different parameters because of the different speed, so a reasonable choice of the turbine speed is also very necessary. In this paper the internal flow of full-speed and half-speed turbine are simulated to compare the difference of the wetness, mash number and pressure distribution by CFX,which may analyze the mutual influence among the three thermal parameters further. The simulation results can provide a reference about nuclear turbine proposal：
