摘要
本文根据水涡轮机械叶栅中的流动特点,导出了反映水涡轮机械流动在径向上变化的三维平衡方程,并推导出了水涡轮机械叶栅内部沿周向平均的流动特性在径向上径变化的平衡方程。这些方程很好地反映了在设计中通常所做的假设的近似性,它们有助于解析水涡轮机械叶栅内的流动,对水涡轮机械的优化设计和性能预测起着重大作用。
A 3-D radial equilibrium motion equation is derived that describes the radial variation of now properties inside a water turbomechine blade row. Another equation is also obtained that describes the radial variation of circumferential-average flow properties inside water turbomachine blade row. These two equations reflect perfectly the approximate degree of the supposition used in design. They are helpful for analysis of the flow inside a water turbomachine blade row. And they play an important role in optimum design and performance prediction of a water turbomachine.
