| 摘 要： | 本文在考虑水流阻力的情况下,提出计算等空化数曲线的方程组,并给出电算程序。实例计算表明,在其他条件相同时,计入水流阻力较之在理想流假定下所得的等空化数曲线,可使溢流面具有更低的空化水头。

| Abstract: | This paper gives, from the energy equation for rapidly varied flow, the equations for the calculation of the curve of equal cavitation number in consideration of friction losses. For the convenience of calculating, a computer program is given. The example demonstrated that the cavitation head
(the head corresponding to the minimum cavitation number) can be reduced than that of the potential flow regardless the friction losses |
