volute diffuser

It is found that vane diffuser restrains the influence of the volute on the impeller.

发现了叶片扩压器对遏制蜗壳对叶轮内流场的影响有明显的作用.

Under the environment of Visual C++ 6.0, the parametric 3-D modeling software PCAD-3D is developed, which includes column blade, curved blade, double channel impeller, volute and radial vaned diffuser, etc.

在Visual c++6.0编程环境下，开发了扭曲叶片、圆柱叶片、双流道叶轮、蜗壳和径向导叶等的参数化三维造型软件PCAD-3D。

Using software PRO-E to build the model of the impeller 、 diffuser with blade 、 entering air elbow 、 volute.

用PRO-E软件对进气弯管，带分流叶片的叶轮及有叶片扩压器进行了实体建模。
