摘要
衡量汽轮机内部工质流动损失大小的阻力特性系数较多,容易造成混淆。因此,为了从理论上理清各阻力特性系数的概念及它们之间的关系,详细阐明了喷嘴各阻力特性系数的定义方法,并推导出了不同阻力特性系数之间的关系表达式,从而为汽轮机叶栅的设计和合理地选取阻力特性系数提供了参考。
Considering the fact that more resistance characteristic coefficients which applied to measuring the internal working fluid＇ s flow loss in the steam turbine can cause concept confusion, theoretically clarifying the concept on resistance characteristic coefficients and their relationship was implemented, including the definition methods for each nozzle＇ s resistance characteristics coefficients and their relation expressions so as to provide the reference for steam turbine cascade design and reasonable selection of the resistance characteristics coefficient.
