| 摘 要： | 采用离心压气机计算机辅助集成设计系统,设计了两个不同子午形面和叶片角的离心压气机叶轮.对这两个离心压气机叶轮内部流场进行了三维粘性计算,给出了计算结果.计算结果表明,在一定范围内,降低叶片轮缘-轮毂方向的负荷可以提高叶轮效率,后加载方式可以改善离心压气机叶轮性能.叶轮进口尺寸相同的情况下,子午形面和叶片角的变化对叶片负荷分布有较大影响.

| Abstract: | Two centrifugal compressor impellers with different meridional shape and blade angle were designed using computer-aided integrated design systems. The flow fields of the impellers were calculated by solving three-dimensional Navier-Stokes equations. Calculation results illustrate that decreasing the blade hub-to-shroud loading level can increase the impeller adiabatic efficiency, and that aft-loaded impeller can obtain higher impeller adiabatic efficiency. Changing meridional shape and blade angle can have large effects on the blade loading distribution. |
