扩压器设计考虑了几种扩压器结构,并进行了初步设计研究用来考查三种候选扩压器几何形状的性能。这些分析的主要结果陈述于以下各节中。常用叶片扩压器这一类型扩压器是许多最近为离心式压气机用的“航空研究”设计的典型。初步提出的 Diffuser Design Several diffuser configurations were considered and preliminary design studies were performed to examine the performance of the three candidate diffuser geometries. The main results of these analyzes are presented in the following sections. Common Blade Diffuser This type of diffuser is typical of many of the “aeronautical research” designs recently used for centrifugal compressors. Initially proposed
