It is not only used to design centrifugal pump impeller and diffuser, but also used to design non_clogging pump impeller and diffuser, radial diffuser, space diffuser, etc.

它除了可进行清水泵的叶轮、蜗壳水力设计外，还可设计无堵塞泵的叶轮、蜗壳以及径向导叶、空间导叶等水力件的水力设计。

The numerical results indicate that the separation flow in axial and radial diffuser was severely, especially in the axial diffuser, which could decrease the efficiency of this centrifugal compressor.

在堵塞状态时径向扩压器和轴向扩压器中都存在不同程度的分离，尤其是轴向扩压器中分离现象更为严重，这些都造成了不同程度的气流损失，导致了效率的降低；

In the whole flow range, the impeller operates under subsonic condition and the radial diffuser operates under transonic condition, thus the choked mass flow rate is determined by the throat area of the radial diffuser.

整个特性线范围内离心叶轮基本在亚音速情况下工作，而径向扩压器是在跨音速条件下工作，离心压气机整机的最大流量是由径向扩压器的喉部面积决定的；
