若压气机工作轮以及叶片扩压器的最大效率已定,则高速径向压气机的特性曲线基本上决定于导风轮以及叶片扩压器喉部的断面积。对于设定的27个压气机几何尺寸的估算结果表明了导风轮叶片入口角度β_1,叶片扩压器喉部面积与工作轮进口面积之比A_D/A_1以及工作轮外径与导风轮均方根直径之比E对压气机性能的影响。实验研究证明了由于在导风轮内以及叶片扩压器内的气流分离现象(或称气流失速)所引起压气机喘振的大致范围进行了讨论。同时也把压气机的实验特性与估算出的特性曲线进行了比较。
If the maximum efficiency of the compressor wheel and the vane diffuser has been set, the characteristic curve of the high-speed radial compressor basically depends on the cross-sectional area of the guide vane and the vane diffuser throat. The estimation of the 27 compressor geometry shows that the inlet angle of the wind turbine blade β_1, the ratio of the throat area of the vane diffuser to the inlet area of the working wheel, A_D / A_1, and the outer diameter of the working wheel and the mean diameter Effect of square root diameter ratio E on compressor performance. Experimental studies have demonstrated the approximate range of compressor surge due to airflow separation (or flow stall) within the wind deflector and vane diffuser. The experimental characteristics of the compressor are also compared with the estimated performance curves.
