cavitation number

Drag coefficient Cd as a function of cavitation number;

阻力系数随空泡数的变化规律；

With the decrease of cavitation number, the loss increase further.

且随着空化系数的降低，损失增加。

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.

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。

However, for bulb turbine, the discharge is large, the number of runner blades is less, the total area is small, cavitation coefficient is large, Intensity condition is bad, as a result, the application head is limited.

但由于贯流式水轮机转轮叶片数少，叶片总面积少，而过流量又较大，气蚀系数大，且叶片强度条件差，故其适用水头是有限的。
