| 摘 要： | 汽轮机末几级内蒸汽的凝结流动对机组效率及安全运行都会产生重大影响,但对这种双相流动的研究却比较困难,因此有必要对透平叶栅内蒸汽的凝结过程进行深入的研究。Bakhtar等通过特殊设计的实验装置,在平面叶栅上对某次末级叶栅进行了实验研究。对其实验结果进行了亚音速条件下的数值模拟研究,以期对该流动机理有深入一些的了解。

| Abstract: | The condensing flow of the steam in turbine last stages will have great influence on the unit efficiency and the safe operation,but it is difficult to study this two-phase flow,so it is necessary to further investigate the condensing process of the steam in turbine cascade.Bakhtar and his cooperators test investigated the second last stage in the linear cascade by the special designed test equipment.The present paper numerical simulated the test results with the subsonic flow condition,want to understand th... |
